Question

A pizza was cut into 12 pieces. After lunch, 5/12 of a pizza was left over. Then Santa ate 1/4 of a pizza. What part of the pizza was left when Santa finished eating?

Answer 1

To answer this question, we have to substract 1/4 (which is the part of the pizza Santa ate) from 5/12 (the part of the pizza that was left over).

$\frac{5}{12}-\frac{1}{4}=\frac{20-12}{48}=\frac{8}{48}=\frac{1}{6}$

1/6 of the pizza was left when Santa finished eating.
