Understanding the Problem: 4.735 x 6

Before diving into the solution, let's break down the problem. We are tasked with multiplying the decimal number 4.735 by the whole number 6. This involves understanding place values and how they shift during multiplication. The number 4.735 has a decimal point, which separates the whole number part (4) from the fractional part (.735). Each digit after the decimal point represents a fraction: the first digit (7) is in the tenths place, the second digit (3) is in the hundredths place, and the third digit (5) is in the thousandths place. When we multiply a decimal by a whole number, we essentially scale the decimal value. In this case, we are scaling 4.735 six times. To perform this multiplication accurately, we need to account for the decimal places. The strategy we will employ is to multiply the numbers as if they were whole numbers, and then adjust the decimal point in the final answer. This approach simplifies the process and reduces the chances of error. Think of it this way: we are temporarily ignoring the decimal point to make the multiplication easier, and then we will bring it back in at the end. This technique is widely used and is a cornerstone of decimal multiplication. By understanding the structure of the problem and the values involved, we set the stage for a successful calculation. The goal is not just to arrive at the correct answer but to understand the reasoning behind each step, so you can apply this knowledge to other decimal multiplication problems. Now, let's move on to the step-by-step solution, where we'll break down the multiplication process in detail.

Step-by-Step Solution

To solve 4.735 x 6, we will follow these steps:

  1. Ignore the Decimal: Initially, treat 4.735 as if it were a whole number, 4735. This simplifies the multiplication process, allowing us to focus on the digits themselves without the added complexity of the decimal point. By temporarily ignoring the decimal, we transform the problem into a more familiar form of multiplication that most people find easier to handle. This is a common technique in decimal multiplication, making the process less intimidating. Think of it as a temporary simplification to make the arithmetic easier. Once we have the product of the whole numbers, we will reintroduce the decimal point in the appropriate place. This method is both efficient and accurate, ensuring that we arrive at the correct answer without confusion. So, for the moment, let's set aside the decimal point and focus on multiplying 4735 by 6. This will give us an intermediate result that we will adjust later to account for the decimal places.

  2. Multiply as Whole Numbers: Multiply 4735 by 6. This is a standard multiplication problem that can be solved using the traditional long multiplication method. Start by multiplying 6 by each digit of 4735, starting from the right (the ones place) and moving left. Here’s how it breaks down:

    • 6 x 5 = 30 (write down 0, carry over 3)
    • 6 x 3 = 18 + 3 (carried over) = 21 (write down 1, carry over 2)
    • 6 x 7 = 42 + 2 (carried over) = 44 (write down 4, carry over 4)
    • 6 x 4 = 24 + 4 (carried over) = 28 (write down 28)

    So, the result of 4735 x 6 is 28410. This intermediate result is crucial, as it forms the basis for our final answer. However, we are not quite done yet. We need to account for the decimal point that we temporarily ignored. The next step will focus on placing the decimal point correctly to arrive at the final, accurate answer. This process is critical in ensuring the result reflects the true value of the decimal multiplication. By breaking down the multiplication into manageable steps, we reduce the likelihood of errors and gain a clearer understanding of the process.

  3. Count Decimal Places: In the original number, 4.735, there are three decimal places (the digits 7, 3, and 5 after the decimal point). This is a crucial piece of information for placing the decimal point in our final answer. The number of decimal places in the result must match the number of decimal places in the original decimal number. In this case, since 4.735 has three decimal places, our final answer will also have three decimal places. This rule ensures that the value of the result is proportionate to the original numbers. It’s a fundamental concept in decimal multiplication and division. By accurately counting the decimal places, we maintain the integrity of the calculation and avoid errors that can significantly alter the result. So, remember, the number of decimal places in the product is the same as the number of decimal places in the original decimal number. This principle guides us in placing the decimal point correctly and obtaining the accurate solution.

  4. Place the Decimal: Starting from the right in our result (28410), count three places to the left and place the decimal point. This step is the key to converting our whole number product back into a decimal value. Since we counted three decimal places in the original number, we count three places from the right in our result. So, in 28410, we count three places from the right: 0, 1, 4, and then place the decimal point. This gives us the number 28.410. The placement of the decimal point is critical because it determines the magnitude of the number. Placing it incorrectly can result in an answer that is significantly larger or smaller than the true value. By carefully counting the decimal places and placing the decimal point accurately, we ensure the integrity of our calculation and arrive at the correct result. This step demonstrates the importance of precision in mathematical operations and the need for a systematic approach to problem-solving.

  5. Final Answer: Therefore, 4.735 x 6 = 28.410, which can be simplified to 28.41 (since the trailing zero does not change the value). This is our final, accurate answer. We have successfully multiplied a decimal number by a whole number by following a clear, step-by-step process. This result aligns with the magnitude we would expect when scaling 4.735 six times. It's a testament to the effectiveness of breaking down complex problems into manageable steps. By understanding each step, from ignoring the decimal initially to placing it correctly in the final result, we gain confidence in our ability to solve similar problems. The answer 28.41 is not just a number; it represents the scaled value of 4.735 after being multiplied by 6. It's a practical application of mathematical principles that has real-world relevance, from calculating costs to measuring quantities. So, with this solution in hand, we can confidently move on to more complex mathematical challenges.

Identifying the Correct Option

Now that we have calculated the result, 28.41, we need to identify the correct option from the given choices:

  • F 28.41
  • G 0.2841
  • H 2.841
  • J 284.1
  • K None of these

Clearly, option F, 28.41, matches our calculated result. This step is crucial in any problem-solving scenario, as it confirms that our calculations align with the available choices. It's a moment of validation, where we see the direct application of our work. Identifying the correct option requires careful comparison and attention to detail. It’s not just about getting the calculation right; it’s also about ensuring that we select the corresponding answer from the given possibilities. This step reinforces the importance of accuracy and precision in both calculation and selection. Option F stands out as the perfect match, affirming the correctness of our approach and the accuracy of our result. It's a satisfying conclusion to a well-executed mathematical problem.

Common Mistakes to Avoid

When multiplying decimals, there are several common mistakes that can lead to incorrect answers. Being aware of these pitfalls can help you avoid them and improve your accuracy:

  1. Miscounting Decimal Places: One of the most frequent errors is miscounting the number of decimal places. Always double-check the original number and ensure you place the decimal point in the correct position in the final answer. This is a critical step, as the placement of the decimal point determines the magnitude of the number. A simple miscount can result in an answer that is significantly larger or smaller than the correct value. To avoid this, take the time to count the decimal places carefully and verify your count before placing the decimal point in the result. Accuracy in this step is paramount to achieving the correct solution.

  2. Forgetting to Carry Over: In the multiplication process, forgetting to carry over digits can lead to significant errors. Ensure you add the carried-over digits in each step to maintain accuracy. Carrying over is a fundamental aspect of multiplication, and neglecting it can distort the result. It's essential to be meticulous in this process, as even a single missed carry-over can affect the entire calculation. Practice and attention to detail are key to mastering this aspect of multiplication and avoiding errors. By consistently checking your work and ensuring that all carry-over digits are accounted for, you can minimize the risk of making this common mistake.

  3. Incorrect Multiplication: Simple multiplication errors, such as miscalculating basic multiplication facts, can also occur. Double-check your multiplication steps to ensure accuracy. Even the most seasoned mathematicians can make occasional multiplication errors, so it's always wise to verify your work. These errors can stem from distractions, lapses in concentration, or simply forgetting a multiplication fact. To mitigate this, take a methodical approach to multiplication, breaking it down into smaller, manageable steps. If possible, use estimation to check if your intermediate results are reasonable. By being vigilant and double-checking your calculations, you can catch and correct these errors before they lead to an incorrect final answer.

  4. Ignoring Trailing Zeros: Trailing zeros to the right of the decimal point, but after a non-zero digit, should be included in the answer (e.g., 28.410 is equivalent to 28.41). However, ignoring these trailing zeros initially can sometimes lead to confusion. While trailing zeros at the end of a decimal don't change its value, it's important to include them in the intermediate steps to maintain clarity. This ensures that you are accurately accounting for all decimal places and prevents any potential misinterpretations. Once you have the final answer, you can simplify it by removing any unnecessary trailing zeros, but it's crucial to consider them during the calculation process. This attention to detail helps in avoiding confusion and ensuring the accuracy of your result.

By being mindful of these common mistakes, you can significantly improve your accuracy and confidence in multiplying decimals. Decimal multiplication is a skill that improves with practice, and by learning from your mistakes, you can develop a solid understanding of the process.
