Answer:
We are all told that fractions can be considered as a cake, since you are introduced to divisions and fractions.
Now, 2/7, in the cake example, is 2 slices of cake when 1 cake is sliced to 7 equal parts.
Think about having a full cake (1), we cut it into 7 equal parts and remove 2 parts of it. How many parts do we have left? 5! So we can represent the remaining cake as 5/7 of the original cake(1). This is the subtraction side of story.
What about the addition side? We have 2 slices now, how many equal sized slices to make it a full cake? 5! That’s why we add 5/7 to the 2/7 cake to make it a full cake!
More advanced, algebric way:
2/7 + ? = 1
Moving 2/7 to RHS, we have
?=1–2/7 = 7/7 - 2/7 = (7–2) / 7 = 5/7
OR
2/7 + ? = 1
2/7 + 1 * ? = 1
2/7 + 7/7 * ? = 1
(2+7*?) / 7 = 1
(2+7*?) = 7
7*? = 5
? = 5/7
