Question

While watching a movie, Ned, Fred, and Jed shared a bowl of popcorn. Ned ate 1/2 of the popcorn, Fred ate 1/4 of the popcorn, and Jed ate 1/8 of the popcorn. What fraction of the bowl of popcorn is left?

Answer 1

1/8 bowl.
1/2 = 4/8
1/4 = 2/8
1/8 = 1/8

4/8+2/8+1/8 = 7/8
1 - 7/8 = 1/8

Answer 2

The fraction of the bowl of popcorn left is 1/8.

Explanation:

The bowl (or generally, any type of container) of the corn is considered to be a whole portion = 1

In order to find the fraction of the bowl of popcorn left over, subtract the portion that Ned, Fred and Jed ate respectively, from 1:

1 ―1/2 ― 1/4 ― 1/8 = 1 ― 7/8 = 1/8
