Place the decimal point in the sum or difference so that it lines up vertically with the decimal points in the problem. 02 7 10 2. 8 0 -1. 0 4 1. 7 6 25. 7 3 2 Step 1. Multiply the decimals as though they are whole numbers. Step 2. The decimal point in the product is placed so that the number of decimal places in the product is equal to the sum of the number of decimal places in the factors. TO DIVIDE DECIMALS Step 1. Move the decimal point in the divisor to the right until the divisor is a whole number.
