Final answer:
To find the total number of pieces of pie left over, add up the fractions that represent the remaining pieces: 1/8 of the apple pie, 1/2 of the cherry pie, and 1/4 of the pumpkin pie.
Step-by-step explanation:
To find the total number of pieces of pie left over, we need to add up the fractions that represent the remaining pieces. The apple pie has 1/8 left, the cherry pie has 1/2 left, and the pumpkin pie has 1/4 left. Let's find a common denominator for these fractions.
The common denominator for 8, 2, and 4 is 8. So, we convert all the fractions to have a denominator of 8:
Apple pie: 1/8 x 1/1 = 1/8
Cherry pie: 1/2 x 4/4 = 4/8
Pumpkin pie: 1/4 x 2/2 = 2/8
Now we can add up these fractions:
1/8 + 4/8 + 2/8 = 7/8
Therefore, there are 7 out of 8 pieces of pie left over
