Final answer:
To find out how many slices you ate with a percent eaten, multiply the total number of slices by the percentage eaten and divide by 100.
Step-by-step explanation:
In order to find out how many slices you ate with a percent eaten, you need to know the total number of slices in the pie and the percentage of the pie you ate.
To calculate the number of slices you ate, multiply the total number of slices by the percentage eaten and divide by 100.
For example, if there are 8 slices in the pie and you ate 25% of it, you would calculate: (8 slices) x (25%) / (100%) = 2 slices.
