#### Worksheet Overview

In this activity, we will solve problems by adding and subtracting mixed number fractions.

As you know, when adding and subtracting fractions, the denominators must be the same first!

Recap

Step 1

Convert any mixed number fractions to improper fractions:

Step 2

Rewrite the question with improper fractions:

Step 3

We look for the lowest common multiple of the denominators 2 and 3 = 6

Multiply fractions to make them equivalent:

Step 4

Step 5

Convert back to a mixed number:

# 11 ÷ 6

We do the same for subtraction, but at step 4 we would  do 9 - 2 instead of 9 + 2

Let's have a go at some questions now.
