 - Multiply a decimal by a one-digit whole number To multiply a decimal by a one-digit whole number, count the decimal places in the factors, multiply, and move the decimal point one place to the left for each decimal place you counted. Multiply 8.3 x 9 = Multiply as you would multiply whole numbers. Count the number of decimal places in the factors. There are 1 decimal places in 8.3. Move the decimal point 1 places to the left in the answer. 747. → 74.7 Write the answer: Multiply 3.8 x 3 = Solution:
