Part B What fraction of all three of the pizzas purchased for the party was eaten? Explain how you got your answer.

Part C Only six guests ate pizza at the party. If all of them ate the same amount, what fraction of one pizza did each person eat? Explain how you got your answer.

Answer 1

leftover fraction is 1 - (1/3 + 1/4 + 1/6) = 1 - 3/4 = 1/4 Answer

B. First pizza:- 1 - 1/3 = 2/3 had been eaten.
Second pizza:- 1 - 1/4 = 3/4 was eaten.
Third pizza:- 1 - 1/6 = 5/6 was eaten.
C.
Total amount of pizza eaten = 3 - 3/4 = 9/4 = 2 1/4
Amount eaten per person = 9/4 / 6 = 3/8 of a pizza
