Question

Serena ate 1/4 of a pie and then eek it 3/4 of the same pie the next day Casey ate 2/3 of the pie that was left what fraction of the original pie was not eating

Answer 1

The fraction of the original pie that was not eaten is given as follows.

Given,

Serena ate 1/4 of a pie.

Serena ate 3/4 of the same pie the next day.

Casey ate 2/3 of the same pie that was left.

A total of a pie is 1.

Let the original fraction of pie that was left uneaten be = x

Therefore, we have,

1/4 + 3/4 + 2/3 + x = 1

(3 + 9 + 8)/12 + x = 1

20/12 + x = 1

x = 20/12 - 1

x = 8/12

∴ x = 2/3

Therefore the fraction of the original pie that was not eaten is 2/3.
