Final answer:
To determine the numerator for the remaining slices of a pie cut into 16 equal parts after taking 7 slices, subtract 7 from 16, which leaves you with 9 remaining slices. Thus, the numerator for the fraction of pie remaining is 9.
Step-by-step explanation:
If a pie is cut into 16 equal parts and you take 7 slices, the numerator for the remaining slices would be the number of slices that are left. To determine the numerator for the remaining slices of a pie cut into 16 equal parts after taking 7 slices, subtract 7 from 16, which leaves you with 9 remaining slices.
Thus, the numerator for the fraction of pie remaining is 9. To find this number, subtract the slices you've taken from the total number of slices.
Step 1: List the known quantities. The total number of slices is 16, and the number of slices taken is 7.
Step 2: Subtract the number of slices taken from the total to find the remaining slices.
16 slices - 7 slices taken = 9 slices remaining
Therefore, the numerator for the fraction of the pie that remains would be 9, since 9 out of 16 slices are left.
