Breaking Down the Calculation
When faced with an expression like 13.4 x 0.05 x 1.8, it is crucial to approach it systematically to avoid errors. The first step is to recognize that multiplication is associative, meaning the order in which we multiply the numbers does not affect the final result. This gives us the flexibility to choose the most convenient order to simplify the calculation. One effective strategy is to start by multiplying the two numbers that seem easiest to handle together. In this case, multiplying 13.4 by 0.05 first might seem less straightforward than multiplying 0.05 by 1.8. Therefore, we can rearrange the expression and begin with 0.05 x 1.8. This approach not only simplifies the initial steps but also allows us to progressively build towards the final answer. By breaking down the problem into smaller, more manageable parts, we reduce the chances of making mistakes and gain a clearer understanding of the overall process. This step-by-step methodology is applicable to a wide range of mathematical problems, making it a valuable skill to develop. So, let's begin by focusing on the multiplication of 0.05 and 1.8 and proceed from there.
Step 1: Multiplying 0.05 by 1.8
To begin, let's focus on the multiplication of 0.05 and 1.8. This step is crucial as it sets the foundation for the rest of the calculation. When multiplying decimals, it's often helpful to temporarily ignore the decimal points and treat the numbers as whole numbers. So, we can think of this as 5 multiplied by 18. This simplification makes the initial multiplication easier to perform. 5 multiplied by 18 equals 90. Now, we need to account for the decimal places. In the original numbers, 0.05 has two decimal places, and 1.8 has one decimal place. Therefore, the product will have a total of three decimal places (2 + 1 = 3). Placing the decimal point three places from the right in 90 gives us 0.090, which is the same as 0.09. Thus, the result of multiplying 0.05 by 1.8 is 0.09. This step-by-step approach ensures accuracy and helps in understanding the underlying principles of decimal multiplication. With this result in hand, we can move on to the next step, which involves multiplying 0.09 by the remaining number in the original expression.
Step 2: Multiplying 13.4 by 0.09
Now that we've calculated the product of 0.05 and 1.8, which is 0.09, the next step is to multiply 13.4 by 0.09. This multiplication will give us the final answer to the original expression. Similar to the previous step, we can initially ignore the decimal points for ease of calculation. We can think of this as multiplying 134 by 9. Performing this multiplication gives us 1206. Next, we need to consider the decimal places. In the numbers we are multiplying, 13.4 has one decimal place, and 0.09 has two decimal places. This means the product will have a total of three decimal places (1 + 2 = 3). Placing the decimal point three places from the right in 1206 gives us 1.206. Therefore, the result of multiplying 13.4 by 0.09 is 1.206. This completes the calculation, providing us with the final answer to the expression 13.4 x 0.05 x 1.8. The step-by-step breakdown ensures that each part of the calculation is handled accurately, leading to a correct final result.
The Final Answer
After meticulously performing each step, we have arrived at the solution for the expression 13.4 x 0.05 x 1.8. We initially multiplied 0.05 by 1.8, which resulted in 0.09. Then, we multiplied 13.4 by 0.09, which yielded the final answer. Therefore, the final answer to 13.4 x 0.05 x 1.8 is 1.206. This result is the culmination of a series of careful calculations, highlighting the importance of a systematic approach to mathematical problems. By breaking down the expression into smaller parts and addressing each part methodically, we were able to arrive at the correct solution. This process not only provides the answer but also reinforces the understanding of decimal multiplication and the order of operations. The result, 1.206, is not just a number; it represents the successful application of mathematical principles and techniques.
