Question

Roberto ate 3 pieces of a pizza and them felt that he should pay 1/4 of the cost because that's the fraction he ate. How many pieces was the pizza cut into? Please could you explain me the problem and you give me the answer? thank you

Answer 1

Let x equal the total number of pieces.

1/4 = 3/x

Cross multiply.

x = 12

Doesn't 1/4 = 3/12?
