# Multiplying fractions review

CCSS Math: 5.NF.B.4

Review the basics of multiplying fractions, and try some practice problems.

## Multiplying fractions

To multiply fractions, we multiply the numerators and then multiply the denominators.

**Example 1: Fractions**

**Example 2: Mixed numbers**

Before multiplying, we need to write the mixed numbers as improper fractions.

$= ~\dfrac{8}3 \times \dfrac{8}5$ $\qquad$

We can also write this as $4\dfrac4{15}$ .

### Cross-reducing

Cross-reducing is a way to simplify before we multiply. This can save us from dealing with large numbers in our product.

**Example**

$=\dfrac{\stackrel{1}{\cancel{3}} \times ~1 }{ 10\times \underset{2}{\cancel{6}}} \qquad$
