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.
