Hannah sliced a pie into 12 equal pieces.Hannah and her brothers ate 3 of the 12 slices.
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

  • Math -

    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
