Del and his 5 friends eat 4 pizzas. If each has the same amount and there is 1/4 of a pizza left over, how much did each person eat?

This means 4 full pizzas - 1/4 of a pizza = 3 & 3/4 pizzas eaten

Del and his 5 friends means 6 people total. Since they ate equal amounts, we divide pizzas eaten by total people:

3 & 3/4 / 6

Convert 3 & 3/4 to a mixed fraction:
(4*3 + 3)/4 = 15/4

15/4/6

Divide by a fraction is the same as multiply by a reciprocal:
15/4 * 1/6 = 15/24 pizzas per person
