Question

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

Answer 1

12 - 3 = 9 pieces they didn't eat

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
