Understanding the Basics of Fraction Multiplication

Before diving into the specifics of multiplying 8/11 by 3/2, it’s essential to grasp the foundational principles of fraction multiplication. A fraction, represented as a/b, consists of two main components: the numerator (a) and the denominator (b). The numerator indicates the number of parts we are considering, while the denominator represents the total number of equal parts the whole is divided into. When multiplying fractions, we are essentially finding a fraction of a fraction. The rule for multiplying fractions is straightforward: multiply the numerators together to get the new numerator, and multiply the denominators together to get the new denominator. This process can be summarized as (a/b) × (c/d) = (a × c) / (b × d). Understanding this basic rule is the cornerstone of mastering fraction multiplication. It allows us to efficiently combine fractions and arrive at a product that represents the combined proportion of the original fractions. This fundamental principle will be applied throughout our exploration of the problem, ensuring a clear and concise understanding of each step.

Applying the Rule: Multiplying 8/11 by 3/2

Now, let's apply the basic rule of fraction multiplication to our specific problem: 8/11 × 3/2. Following the rule (a/b) × (c/d) = (a × c) / (b × d), we multiply the numerators (8 and 3) and the denominators (11 and 2) separately. Multiplying the numerators gives us 8 × 3 = 24, and multiplying the denominators gives us 11 × 2 = 22. Therefore, the initial product of the fractions is 24/22. This fraction represents the result of multiplying 8/11 by 3/2. However, it's crucial to recognize that this fraction may not be in its simplest form. To express the answer in its lowest terms, we need to simplify the fraction by finding the greatest common divisor (GCD) of the numerator and the denominator and dividing both by it. This step ensures that our final answer is presented in the most concise and easily understandable format. The next section will delve into the process of simplifying fractions, allowing us to express 24/22 in its lowest terms.

After multiplying fractions, the resulting fraction is often not in its simplest form. Simplifying a fraction means reducing it to its lowest terms, where the numerator and denominator have no common factors other than 1. This process involves finding the greatest common divisor (GCD) of the numerator and denominator and then dividing both by that GCD. The GCD is the largest number that divides both the numerator and denominator without leaving a remainder. There are several methods to find the GCD, including listing factors, prime factorization, and using the Euclidean algorithm. Once the GCD is found, dividing both the numerator and denominator by it simplifies the fraction to its lowest terms. This simplified form is easier to work with and provides a clear representation of the fraction's value. In the context of our problem, simplifying the fraction 24/22 is essential to present the final answer in its most concise and understandable form. The following sections will guide you through the process of finding the GCD and simplifying 24/22.

Identifying the Greatest Common Divisor (GCD)

To simplify the fraction 24/22, we need to identify the greatest common divisor (GCD) of 24 and 22. The GCD is the largest number that divides both 24 and 22 without leaving a remainder. One method to find the GCD is by listing the factors of each number. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 22 are 1, 2, 11, and 22. By comparing the lists, we can see that the common factors of 24 and 22 are 1 and 2. The largest of these common factors is 2, so the GCD of 24 and 22 is 2. Another method to find the GCD is by using prime factorization. The prime factorization of 24 is 2 × 2 × 2 × 3, and the prime factorization of 22 is 2 × 11. The common prime factor is 2, which appears once in both factorizations, so the GCD is 2. Once we have identified the GCD, we can use it to simplify the fraction by dividing both the numerator and the denominator by it. This step is crucial in expressing the fraction in its lowest terms, making it easier to interpret and use in further calculations.

Simplifying 24/22 Using the GCD

Now that we've determined the greatest common divisor (GCD) of 24 and 22 to be 2, we can simplify the fraction 24/22. To do this, we divide both the numerator and the denominator by the GCD. Dividing the numerator, 24, by 2 gives us 24 ÷ 2 = 12. Dividing the denominator, 22, by 2 gives us 22 ÷ 2 = 11. Therefore, the simplified fraction is 12/11. This fraction is in its lowest terms because 12 and 11 have no common factors other than 1. Simplifying fractions is an essential step in expressing mathematical results in their most concise and understandable form. It ensures that the fraction is represented in its simplest possible terms, making it easier to compare and use in further calculations. The simplified fraction 12/11 represents the final result of multiplying 8/11 by 3/2 and expressing the answer in its lowest terms. In the next section, we will discuss how to express this improper fraction as a mixed number for better clarity.

While 12/11 is the correct simplified fraction, it is an improper fraction, meaning the numerator is greater than the denominator. To make the answer more intuitive, it can be converted into a mixed number. A mixed number combines a whole number and a proper fraction (where the numerator is less than the denominator). To convert an improper fraction to a mixed number, we divide the numerator by the denominator. The quotient becomes the whole number part of the mixed number, and the remainder becomes the numerator of the fractional part. The denominator remains the same. In the case of 12/11, we divide 12 by 11. The quotient is 1, and the remainder is 1. Therefore, the mixed number equivalent of 12/11 is 1 1/11 (one and one-eleventh). Presenting the answer as a mixed number can provide a clearer sense of the quantity, especially in practical applications. It helps to visualize the amount as a combination of a whole unit and a fraction of a unit. While not always necessary, converting to a mixed number is a useful skill to have and can enhance understanding and communication of mathematical results.

Converting 12/11 to a Mixed Number

To convert the improper fraction 12/11 to a mixed number, we follow the process of dividing the numerator by the denominator. We divide 12 by 11, which gives us a quotient of 1 and a remainder of 1. The quotient (1) becomes the whole number part of the mixed number, the remainder (1) becomes the numerator of the fractional part, and the denominator (11) remains the same. Therefore, 12/11 can be expressed as the mixed number 1 1/11. This means that 12/11 is equivalent to one whole unit and one-eleventh of another unit. Mixed numbers are often easier to interpret in real-world contexts because they provide a clear sense of the whole units and the fractional part. For example, 1 1/11 can be thought of as slightly more than one whole. While the improper fraction 12/11 is a correct answer, expressing it as a mixed number can enhance understanding and communication, especially in practical situations where the magnitude of the quantity is important. This conversion demonstrates a valuable skill in working with fractions and helps in building a deeper understanding of numerical relationships.

In conclusion, the result of multiplying 8/11 by 3/2, expressed as a fraction in its lowest terms, is 12/11. Furthermore, this improper fraction can be represented as the mixed number 1 1/11. This exercise has demonstrated the step-by-step process of multiplying fractions and simplifying the result.
