What fraction of the pie was NOT eaten?

A.1/3

B.1/4

C.2/3

D.3/4

We did this one together in class and my teacher said it was D

Explain?

I know its not B cause 3/12=1/4

9/12

Divide the numerator and the denominator by 3

9/12 = 3/4

Another way to figure it out is subtract 12/12 - 3/12 = 9/12 = 3/4
