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? 8/16 because 2/16 + 6/16 =
8/16.

⅓ + ⅔ = For this 1 I only added the 2 top numbers and left the 2 bottom numbers as it is.
Then I got the answer to 3/3
⅙ + 2/6 = As for the same I only added the top numbers and got the answer to 3/6
12/25 + 3/25 = The final answer for these 3 answers are 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? 2/21 because 5/21 - 3/21 = 2/21.

½ + 2/4 = First I changed ½ into 2/4 and added both 2/4 which the answer would be 4/4
3/6 + ⅔ = I chose to change 3/6 into ⅔ and as for this I add both ⅔ and the answer is 4/3
⅕ + 2/10 = First I change the 2/10 into ⅕ and add ⅕ + ⅕ which is ⅖
