Question

Keaton and his friends ate 3/4 of a pumpkin pie. His sister then eats 2/3 of what was left. How much of the original pie did she eat?

Answer 1

She ate 1/6 of the entire pie.

Answer 2

Since Keaton and his friends ate 3/4 of the pie, there will be 1/4 of the pie left. Then, his sister ate 2/3 of that amount. So, if you multiply 1/4 and 2/3, you will have your answer. The answer is 2/12, which, when simplified, is 1/6.
