1. Do you remember how to change from a mixed number to an improper fraction?
5 1 2
4 2 7 = = = =

2. CHANGE: A mixed number to Improper Fraction
Multiply the whole number by the denominator
Add your answer to the numerator
Put that number on top of the denominator 1 5 2 = 2 2
The denominator always stays the SAME!

3. Convert the mixed number to an improper fraction:
1) Multiply 2) Add 3) On top! 1 9 4 2 2

4. Convert the mixed number to an improper fraction:2 12 2 5 5

5. Do you remember how to change from an improper fraction to a mixed number?
7 2
13 3
73 9
15 6 = = = = =

6. CHANGE: An Improper Fraction to a Mixed Number4 1 1 = 3 3
How many wholes? And how many parts are left over?

7. Convert the improper fraction to a mixed number:5 1 2 2 2

8. Convert the improper fraction to a mixed number:7 1 2 3 3

9. What is today’s learning objective?

10. Method:
You need to change the mixed number into an improper fraction before you can add them together = =
10 4 =
CHECK!! Are the denominators the same?
When they are, add the numerators together.
2 2 4
=2 1 2
We can change the answer into a mixed number when the numerator is bigger than the denominator.

11. Adding Mixed Numbers 𝟓 𝟒 + 𝟓 𝟑 = 𝟏𝟓 𝟏𝟐 + 𝟐𝟎 𝟏𝟐 = 𝟑𝟓 𝟏𝟐 = 𝟐 𝟏𝟏 𝟏𝟐 𝟓 𝟒
Work out:
You can add the whole numbers first then the fractions in this case but it’s not always easy to deal with the fractions!
My suggestion  always change to an improper fraction first!
Then give your answer as a mixed number:
𝟓 𝟒 + 𝟓 𝟑 = 𝟏𝟓 𝟏𝟐 + 𝟐𝟎 𝟏𝟐 = 𝟑𝟓 𝟏𝟐 = 𝟐 𝟏𝟏 𝟏𝟐
𝟓 𝟒
𝟓 𝟑

12. Subtracting Mixed Numbers
Work out: −1 1 2
You can subtract the whole numbers first then the fractions in this case, but this isn’t always easy!
My suggestion  always change to an improper fraction first!
Then give your answer as a mixed number:
𝟐𝟔 𝟕 − 𝟑 𝟐 = 𝟓𝟐 𝟏𝟒 − 𝟐𝟏 𝟏𝟒 = 𝟑𝟏 𝟏𝟒 = 𝟐 𝟑 𝟏𝟒
𝟐𝟔 𝟕
𝟑 𝟐

13. To Add/Subtract Mixed Numbers
Change the mixed numbers to improper fractions
Add/Subtract fractions as usual
Change the answer back to a mixed number
