Draw 3/4 of 16 smiley faces and 3/4 of 12 smiley faces.
Is 3/4 of 16 less than or greater than 3/4 of 12?
3/4 of 16:

The pie shop sold 16 pies.
One-half of them were apple pies.
One-fourth of them were blueberry pies.
How many pies were not apple or blueberry?
Apple: 1/2 of 16 is 8.
Blueberry: 1/4 of 16 is 4.
How many pies were not apple or blueberry?
Total # of pies - apple and blueberry pies = # of pies that
are not blue berry or apple.
16 - 12 = 4.
Therefore, 4 of the pies were not blueberry or apple.
