Question

Kangunda ate 5/8 of his personal sized pizza. Claire ate 1/2 of hers, Andalee ate 3/4 of hers, and Erik ate 9/16 of his. Who ate the most of his or her pizza?

Answer 1

andalee because she ate 12/16 of her pizza.

if we convert the pizza eaten by everyone into denominator 16 we will  get the following results

kanagunda  10/16

claire   8/16

erik     9/16

andalee  12/16

so andalee ate the most of her pizza
