This lesson will teach you different methods for multiplying a fraction by a whole number.

We will learn two different methods for multiplying mixed numbers and improper fractions.

It is always useful to learn more than one method. Then, you can choose which one you prefer to use to solve different problems accurately and with confidence.

Mixed numbers are numbers that we write with a whole number part and a fraction part.

Improper fractions are fractions with a numerator greater than the denominator.
