The main question is: What is the total number of cups of punch that Peter makes? Understanding how to add mixed numbers is crucial in solving this real-world problem. In this comprehensive guide, we will break down the steps to calculate the total volume of Peter's punch. We will explore the fundamentals of adding mixed numbers and apply these concepts to solve this specific problem. Whether you are a student learning about fractions or someone who enjoys making homemade beverages, this article will provide a clear and concise method for determining the total amount of punch Peter creates. Let’s dive into the details and discover the final quantity of this flavorful beverage.

Understanding Mixed Numbers

Before we calculate the total volume of punch, let's first understand mixed numbers. A mixed number is a combination of a whole number and a proper fraction (where the numerator is less than the denominator). In Peter's recipe, we encounter mixed numbers such as $4 \frac{1}{3}$, $2 \frac{1}{3}$, and $6 \frac{1}{2}$. To effectively add these mixed numbers, we need to either convert them into improper fractions or add the whole numbers and fractions separately. Each method has its advantages, and we'll explore both to provide a comprehensive understanding. Converting to improper fractions involves multiplying the whole number by the denominator of the fraction and adding the numerator. This result becomes the new numerator, while the denominator remains the same. Alternatively, we can add the whole numbers together and then add the fractions separately, simplifying the process if the fractions have a common denominator. Mastering these techniques is essential not only for solving this particular problem but also for various mathematical applications in everyday life. Let’s delve deeper into how these methods work and when each might be more suitable.

Converting Mixed Numbers to Improper Fractions

To effectively add the volumes of the ingredients in Peter's punch, it’s essential to understand how to convert mixed numbers into improper fractions. This method provides a straightforward way to add fractions, especially when dealing with mixed numbers. Let's explore the conversion process step by step. A mixed number consists of a whole number and a proper fraction, such as $4 \frac{1}{3}$. To convert this into an improper fraction, we follow a simple formula: Multiply the whole number by the denominator of the fraction, add the numerator, and place the result over the original denominator. For example, to convert $4 \frac{1}{3}$, we multiply 4 (the whole number) by 3 (the denominator), which equals 12. Then, we add the numerator, which is 1, resulting in 13. This becomes our new numerator, and we keep the original denominator, 3. Thus, $4 \frac{1}{3}$ converts to $\frac{13}{3}$. This conversion method is crucial because it allows us to add fractions more easily, as we only need to ensure the fractions have a common denominator. Let’s apply this method to all the mixed numbers in Peter’s recipe and see how it simplifies our calculations. By mastering this skill, you'll be well-equipped to tackle a wide range of fraction-related problems.

Adding Fractions with Common Denominators

After converting mixed numbers to improper fractions, the next crucial step in calculating the total volume of Peter's punch is understanding how to add fractions with common denominators. This is a fundamental concept in fraction arithmetic and simplifies the addition process considerably. When fractions share a common denominator, it means they are divided into the same number of equal parts. To add these fractions, you simply add their numerators while keeping the denominator the same. For instance, if we have $\frac{2}{5}$ and $\frac{1}{5}$, both fractions have a denominator of 5. To add them, we add the numerators: 2 + 1 = 3. Thus, the sum is $\frac{3}{5}$. This principle applies to any number of fractions with the same denominator. In the context of Peter's punch recipe, once we convert the mixed numbers to improper fractions, we often find that we need to create a common denominator before we can add them. This might involve finding the least common multiple (LCM) of the denominators. However, once a common denominator is established, the addition process becomes straightforward. Adding fractions with common denominators is a cornerstone of fraction operations, making it easier to combine quantities and solve real-world problems like determining the total volume of a mixed beverage. Let’s see how this applies specifically to Peter’s recipe.

Finding a Common Denominator

In mathematics, especially when dealing with fractions, finding a common denominator is a critical skill. It allows us to add or subtract fractions that initially have different denominators. The common denominator is a shared multiple of the denominators of the fractions involved. The most efficient common denominator to use is the least common multiple (LCM) of the denominators. To find the LCM, you can list the multiples of each denominator until you find a number that appears in both lists. For instance, if you have fractions with denominators of 3 and 2, the multiples of 3 are 3, 6, 9, and so on, while the multiples of 2 are 2, 4, 6, 8, and so on. The LCM of 3 and 2 is 6, which becomes the common denominator. Once you've identified the common denominator, you need to convert each fraction to an equivalent fraction with this new denominator. This is done by multiplying both the numerator and the denominator of each fraction by the same number, ensuring the value of the fraction remains unchanged. For example, to convert $\frac{1}{3}$ to a fraction with a denominator of 6, you multiply both the numerator and denominator by 2, resulting in $\frac{2}{6}$. Similarly, to convert $\frac{1}{2}$ to a fraction with a denominator of 6, you multiply both the numerator and denominator by 3, resulting in $\frac{3}{6}$. Finding a common denominator is a foundational step in performing fraction addition and subtraction, making it an indispensable skill for solving problems like calculating the total volume of Peter's punch. Let’s apply this to our specific problem to ensure we can accurately add the volumes of different ingredients.

Adding Mixed Numbers Directly

While converting to improper fractions is a reliable method, another approach to adding mixed numbers is to add the whole numbers and fractions separately. This method can be particularly useful when the fractional parts are easily added or when a common denominator is already apparent. To add mixed numbers directly, first, add the whole number parts together. For instance, if you are adding $4 \frac{1}{3}$ and $2 \frac{1}{3}$, you would add 4 and 2, which equals 6. Next, add the fractional parts. In this case, you would add $\frac{1}{3}$ and $\frac{1}{3}$, which equals $\frac{2}{3}$. Finally, combine the sum of the whole numbers and the sum of the fractions to get the total mixed number. In our example, this would be $6 \frac{2}{3}$. However, there is one additional step to consider: If the sum of the fractions results in an improper fraction (where the numerator is greater than or equal to the denominator), you need to convert this improper fraction back into a mixed number and add its whole number part to the whole number sum you previously obtained. For example, if the fractional parts add up to $\frac{5}{2}$, you would convert this to $2 \frac{1}{2}$ and add the 2 to the whole number sum. Adding mixed numbers directly can be a straightforward method, especially when the fractions have common denominators, but it’s crucial to remember to simplify the result if the fractional part is an improper fraction. Let’s see how we can apply this method to calculate the total volume of Peter's punch.

Step-by-Step Solution for Peter's Punch

Now that we’ve covered the necessary background on mixed numbers and fractions, let's apply these concepts to solve the problem of calculating the total number of cups of punch Peter makes. We’ll break down the solution into clear, manageable steps. First, we identify the quantities of each ingredient: Peter uses $4 \frac{1}{3}$ cups of orange juice, $2 \frac{1}{3}$ cups of ginger ale, and $6 \frac{1}{2}$ cups of strawberry lemonade. The core task is to add these three mixed numbers together to find the total volume of the punch. We can approach this in a couple of ways: either by converting the mixed numbers to improper fractions and then adding them, or by adding the whole numbers and fractional parts separately. Let's start by converting the mixed numbers to improper fractions. $4 \frac{1}{3}$ becomes $\frac{13}{3}$, $2 \frac{1}{3}$ becomes $\frac{7}{3}$, and $6 \frac{1}{2}$ becomes $\frac{13}{2}$. Next, we need to find a common denominator for these fractions. The least common multiple of 3 and 2 is 6, so we will convert all fractions to have this denominator. This step-by-step approach ensures clarity and accuracy in our calculations, making it easier to follow along and understand the process. By meticulously working through each step, we can confidently arrive at the correct answer for the total volume of Peter's delightful punch.

Step 1: Convert Mixed Numbers to Improper Fractions

In the first crucial step of solving this problem, we need to convert the mixed numbers into improper fractions. This conversion is essential for simplifying the addition process. Peter’s recipe includes $4 \frac{1}{3}$ cups of orange juice, $2 \frac{1}{3}$ cups of ginger ale, and $6 \frac{1}{2}$ cups of strawberry lemonade. Let's convert each of these mixed numbers. To convert $4 \frac{1}{3}$ to an improper fraction, we multiply the whole number (4) by the denominator (3), which gives us 12, and then add the numerator (1), resulting in 13. We place this over the original denominator, so $4 \frac{1}{3}$ becomes $\frac{13}{3}$. Next, we convert $2 \frac{1}{3}$. Multiplying the whole number (2) by the denominator (3) gives us 6, and adding the numerator (1) results in 7. Thus, $2 \frac{1}{3}$ becomes $\frac{7}{3}$. Finally, we convert $6 \frac{1}{2}$. Multiplying the whole number (6) by the denominator (2) gives us 12, and adding the numerator (1) results in 13. So, $6 \frac{1}{2}$ becomes $\frac{13}{2}$. By converting these mixed numbers to improper fractions—$\frac{13}{3}$, $\frac{7}{3}$, and $\frac{13}{2}$—we have prepared the ingredients for addition. This step is vital because it transforms the problem into a straightforward addition of fractions, setting the stage for finding a common denominator and calculating the total volume of Peter’s punch. Let’s move on to the next step where we find this common denominator.

Step 2: Find the Common Denominator

The next critical step in calculating the total volume of Peter's punch is to find a common denominator for the improper fractions we obtained in the previous step. We have the fractions $\frac{13}{3}$, $\frac{7}{3}$, and $\frac{13}{2}$. To add these fractions, we need a common denominator, which is the least common multiple (LCM) of the denominators 3 and 2. To find the LCM of 3 and 2, we can list their multiples: Multiples of 3: 3, 6, 9, 12, ... Multiples of 2: 2, 4, 6, 8, ... The smallest number that appears in both lists is 6. Therefore, the LCM of 3 and 2 is 6, and this will be our common denominator. Now that we have identified the common denominator as 6, we need to convert each fraction to an equivalent fraction with this denominator. This involves multiplying both the numerator and the denominator of each fraction by a factor that will make the denominator equal to 6. Finding the common denominator is a fundamental step in adding fractions, as it allows us to combine the quantities accurately. Once we convert each fraction to have a denominator of 6, we can proceed with the addition. Let’s move on to the next step and perform these conversions.

Step 3: Convert Fractions to Equivalent Fractions with the Common Denominator

Having identified the common denominator as 6, we now need to convert each of our improper fractions to equivalent fractions with this denominator. This step ensures that we can accurately add the fractions together. We start with the fraction $\frac{13}{3}$. To convert this to a fraction with a denominator of 6, we need to multiply both the numerator and the denominator by the same factor. Since 3 multiplied by 2 equals 6, we multiply both the numerator and the denominator by 2: $\frac{13}{3} imes \frac{2}{2} = \frac{26}{6}$. Next, we convert the fraction $\frac{7}{3}$. Again, we multiply both the numerator and the denominator by 2 to get the denominator 6: $\frac{7}{3} imes \frac{2}{2} = \frac{14}{6}$. Finally, we convert the fraction $\frac{13}{2}$. To get the denominator 6, we need to multiply both the numerator and the denominator by 3: $\frac{13}{2} imes \frac{3}{3} = \frac{39}{6}$. Now we have successfully converted all the fractions to equivalent fractions with the common denominator of 6. Our fractions are now $\frac{26}{6}$, $\frac{14}{6}$, and $\frac{39}{6}$. With these equivalent fractions, we are ready to add them together, which will give us the total volume of Peter's punch in cups. Let's proceed to the next step to add these fractions.

Step 4: Add the Fractions

Now that we have the fractions with a common denominator, the next step is to add them together. We have the fractions $\frac{26}{6}$, $\frac{14}{6}$, and $\frac{39}{6}$. To add fractions with a common denominator, we simply add the numerators and keep the denominator the same. So, we add the numerators: 26 + 14 + 39. 26 + 14 equals 40, and then adding 39 gives us 79. Therefore, the sum of the numerators is 79. We keep the common denominator, which is 6. So, the sum of the fractions is $\frac{79}{6}$. This improper fraction represents the total number of cups of punch Peter makes. However, it is more helpful to express this as a mixed number to better understand the quantity. In the next step, we will convert this improper fraction back to a mixed number to provide the final answer in a more understandable form. By adding the fractions, we have determined the total volume of the punch in terms of an improper fraction. Converting it to a mixed number will give us a clearer sense of the quantity.

Step 5: Convert the Improper Fraction to a Mixed Number

Our final step in determining the total volume of Peter's punch is to convert the improper fraction $\frac{79}{6}$ back into a mixed number. An improper fraction has a numerator that is greater than or equal to the denominator, which makes it a whole number plus a fraction. To convert $\frac{79}{6}$ to a mixed number, we need to divide the numerator (79) by the denominator (6). When we divide 79 by 6, we get 13 as the quotient and 1 as the remainder. This means that 6 goes into 79 thirteen times with a remainder of 1. The quotient (13) becomes the whole number part of the mixed number. The remainder (1) becomes the numerator of the fractional part, and we keep the original denominator (6). Therefore, the improper fraction $\frac{79}{6}$ converts to the mixed number $13 \frac{1}{6}$. This mixed number represents the total number of cups of punch Peter makes. So, Peter makes $13 \frac{1}{6}$ cups of punch. This final conversion gives us a clear and practical understanding of the total volume of punch, completing our calculation. By following these steps, we have successfully solved the problem and determined the total quantity of Peter’s refreshing beverage.
