Respuesta :
2/3 of the cake would be 2/3 of 15 slices, or 10 slices.
This leaves (15 slices - 10 slices), or 5 slices.
This leaves (15 slices - 10 slices), or 5 slices.
Answer:
5 Pieces were left
Step-by-step 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.
