Answer 1

To multiply decimal numbers, you need to follow these steps: Multiply the numbers as if they were whole numbers, count the total number of decimal places in the original numbers, and put the decimal point in the product so it has the same number of decimal places as the total from the previous step.

Step-by-step explanation:

To multiply decimal numbers, we follow these steps:

1. Multiply the numbers as if they were whole numbers.
2. Count the total number of decimal places in the original numbers.
3. Put the decimal point in the product so it has the same number of decimal places as the total from step 2.

For the given problem, 39.341 × 0.72:

1. Multiply 39341 and 72:
   2825352
2. Count the total number of decimal places in 39.341 and 0.72, which is 5.
3. Put the decimal point in the product so it has 5 decimal places:
   28.25352

Therefore, the correct answer is 28.25352.
