First, we need to find out what fraction of the apple pie was eaten. Since the apple pie was cut into 6 equal slices and they ate 56 slices of that pie, we can calculate the fraction of the pie eaten.
Assuming there was an error in the question stating they ate "56 of the apple pie," since there are only 6 slices, let's clarify that:
If they actually ate all the slices (which is the maximum of 6 slices), that means they ate 6 out of 6 slices, which is equivalent to eating the entire pie, or 1 whole pie (or 100%).
Now for the blueberry pie, which is cut into 12 equal slices, we want to find how many slices they ate if they ate the same fraction.
Since they ate the entire apple pie, this means they also ate the entire blueberry pie, which is:
- 12 slices out of 12 slices of the blueberry pie.
Thus, they ate 12 slices of the blueberry pie.
So, the answer is 12 slices.
