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.
