Answer:
I attach your full answer in the picture below.
Based on the picture, we can affirm that the paper is distributed into eighths.
Because there are 8 squares of the same size
Each square represents one eighth (1/8) of the original size
If we grab all squares (8 of them) and we multiply it with the amount each represents of the paper, we would get the unity (one paper)
8*(1/8) = 1
