Answer:
Mrs. Suarez cut the pizza into 8 equal slices
There are 3 people in her family and they each eat 2 slices
You would take 3*2 to find out how many slices they ate
3*2=6
They ate 6 slices altogether
Therefore they ate 6/8 of the pizza
6/8 reduces down to 3/4
Mrs. Suarez's family ate 3/4 of the pizza.
Hope this helps ;)
