How do you multiply a mixed decimals?

Answer 1

Multiplying mixed decimals is almost just like multiplying whole numbers.

For example:

5.21 * 1.1

You multiply these two numbers as if they didn't have decimal points, and you get 5,731; however, don't forget that you have decimals!

Count the total number of digits after the decimal in each factor. You should get 3 since 5.21 has two digits after the decimal, and 1.1 has one digit after the decimal. 2 + 1 = 3

Since you have 3 for that total, take the product (which is 5,731) and move the decimal point of that 3 spaces to the left.

Your final product is 5.731
