Elyse folded a piece of paper in half 3 times. she then punched 3 holes in the paper. how many holes are in the paper when she unfolds it?

24 holes.

Step-by-step explanation:

Elyse folded a piece of paper in one half then total surfaces of the paper will become 2.

Then the paper with 2 surfaces again folded half. Surfaces formed again will be 2×2 = 4

Similarly, This paper is folded again for the third time then the surfaces become 2×2×2 = 8

Now Elyse punched a hole in this folded paper so the total holes formed will be on all surfaces = 8.

Now if we punch 3 holes then total holes in unfolded paper will be = 8×3 = 24 holes

Therefore, 24 holes will be formed when paper is unfolded.

4 + 5 7/9= 9 7/9
