Fabulous Fractions

We are learning to identify the relationship between fractions.


What is 2/4 of 50? 25

What is ½ of 50? 25

What is 4/4 of 8?   This is the same as 8/8

What is ⅕ of 10? 2

What is 2/10 of 10? 2

What is ⅓ of 12? 4

What is 2/6 of 12? 4

What is 1/13 of 26? 2

What is 2/26 of 26? 2


What do you notice about these fractions?
After the first one the second one has the same answer.

Show your working for the remainder of the problems


I have 2/16 of a cake at a birthday party. I keep going back for more and eat another  6/16 of a cake. What fraction of a cake have I eaten altogether? 2/16 + 6/16 = 8/16

⅓ + ⅔ =  ⅓ + ⅔ = 3/3

⅙ + 2/6 = ⅙ + 2/6 = 3/6

12/25 + 3/25 = 12/25 + 3/25 = 15/25

I have 5/21 of a cake left over from the party. Then I give 3/21 of a cake to my sisters. What fraction of a cake do I have left over? 5/21 + 3/21 = 8/21


½ + 2/4 =  1

3/6 + ⅔ = 1  ⅓
⅕ + 2/10 =  ⅖ / 4/10
