Multiplying and Dividing Decimals

For multiplying decimals:
-  Ignore the decimal point and set up and multiply the numbers as you do with whole numbers.
-  Count the total number of decimal places in both of the factors.
-  Place the decimal point in the product.

For dividing decimals:
-  If the divisor is not a whole number, move the decimal point to the right to make it a whole number. Do the same for the dividend.
-  Divide similar to whole numbers.

Examples:
Example 1.  Find the product.
Solution: Set up and multiply the numbers as you do with whole numbers. Line up the numbers:  Start with the ones place then continue with other digits → . Count the total number of decimal places in both of the factors. There are four decimals digits. (two for each factor and ) Then:

Example 2.  Find the quotient.
Solution: The divisor is not a whole number. Multiply it by to get :
Do the same for the dividend to get .
Now, divide . The answer is .
