5 of my friends are sharing a large chocolate bar.

I have 5/16 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?
11/16
I have 10/21 of a cake left over from the party.
Then I give 6/21 of a cake to my sisters.
What fraction of a cake do I have left over?
4/21


⅓ + ⅔ = 1


¾ + ¾ = 1 2/4


⅕ + ⅗ = 4/5


⅘ - ⅗ = 1/5


5/10 - 1/10 = 4/10


55/60 - 40/60 = 15/60


12/20 + 17/20 = 5/20

Have a go at these!


½ + 3/4 =  1 1/4


2/6 + ⅔ = 1


⅕ + 2/10 = ⅖


2/6 + 4/12 = ⅔


2/5 + 3/15 = ⅗


1/9 + 1/18 = ⅙

2/9 + 4/18 = 4/9
