Answer:
Hassem and his family ate 6 slices of blueberry pie.
Step-by-step explanation:
The question states that Hassem and his family cut the blueberry pie into 10 equal slices.
Hassem and his family ate 3/5 of the apple pie, if they ate the same fraction of the blueberry pie, this implies that Hassem and his family ate 3/5 of the blueberry pie.
Since the blueberry is cut into 10 equal slices, the number of slices Hassan and his family ate is simply 3/5 of 10 = × 10 = = 6 slices.
Therefore, Hassem and his family ate 6 slices of blueberry pie.
