Multiply the decimals inside parentheses as though they were both whole numbers. Place the decimal point in the product by counting the number of decimal places in each factor.
150.183
Practice makes perfect
We are asked to evaluate the following expression.
0.9(8.2* 20.35)
Let's first find the product in the parentheses. We multiply just as we do with two whole numbers. At first, we ignore any decimal points.
Then we place the decimal point in the product by counting the number of decimal places in each factor.
We found that the product inside the parentheses is 166.870, or just 166.87.
0.9( 8.2* 20.35)=0.9( 166.87)
We will find this product similarly. First, we multiply without decimal points, 9* 16 687=150 183. Now we will place the decimal point.
