Question

Write a multiplying problem involving decimals. Both decimals must include hundredths. Show your work.

Answer 1

To multiply decimals, ignore the decimal points and multiply as if they were whole numbers. Count the total number of decimal places in the original numbers and place the decimal point in the product that many places from the right.

Step-by-step explanation:

To write a multiplying problem involving decimals, we can use the example of multiplying 0.75 by 2.4. To multiply decimals, we can ignore the decimal points and multiply as if they were whole numbers. Then, we count the total number of decimal places in the original numbers and place the decimal point in the product that many places from the right. In this case, 0.75 has 2 decimal places and 2.4 has 1 decimal place, so the product will have a total of 3 decimal places. Let's calculate:

1. Ignore the decimal points: 75 multiplied by 24.
2. Multiply the whole numbers: 75 multiplied by 24 is 1800.
3. After multiplying the whole numbers, count the total number of decimal places in the original numbers (2 + 1 = 3) and place the decimal point in the product 3 places from the right.
4. So, the product of 0.75 and 2.4 is 1.8.
