Question

Sophia bought a large cake and cut it into fifteen slices for her birthday her friends ate 2/3 of the cake how many pieces of the cake were left

Answer 1

5 Pieces were left

Explanation:

First, we must find how many pieces 2/3 is. To do that, we multiply 15 by 2/3= 10. So Sophia's friends ate 10 slices. Then, we subtract 15-10=5. Therefore, there were 5 pieces of cake left.

Answer 2

2/3 of the cake would be 2/3 of 15 slices, or 10 slices.

This leaves (15 slices - 10 slices), or 5 slices.
