If mrs. Valdas ate 4 pieces of a pizza and had 8 left over. What fraction of the pizza was not eaten?

Answer 1

A fraction is part/whole

In this case it would be

part of the pizza not eaten/number of pieces in the whole pizza = 8/12

This can be reduced by dividing both the numerator and denominator by the GCF (Greatest Common Factor)

(8/4)/(12/4) = 2/3 of the pizza is not eaten
