Multiplying Fractions and Whole Numbers

You can multiply fractions by whole numbers in one of two ways:

1. The numerator of the product will be the whole number times the
fraction’s numerator, and the denominator will be the fraction’s
denominator.
2. Treat the whole number as a fraction—the whole number over
one—then multiply as you would any two fractions.
