Four mice: White, Gray, Fat, and Thin were dividing a piece of cheese. They cut it into 4 visually identical slices. Some slices had more holes, so Thin's slice weighed 20 grams less than Fat's, and White's slice weighed 8 grams less than Gray's. However, White was not upset because his slice weighed exactly one quarter of the total weight of the cheese.

Gray cut off 8 grams from his piece, and Fat cut off 20 grams. How should the mice divide the resulting 28 grams of cheese so that everyone has an equal amount of cheese? Don't forget to explain your answer.
Notice that now the slice of Gray weighs as much as the slice of White, i.e., exactly a quarter of the total cheese mass. This means that both White and Gray have already received their share, and all 28 grams should be divided between Fat and Thin. Currently, they have an equal amount of cheese, so they should receive an equal amount, i.e., 14 grams each.

## Answer

Fat and Thin should take 14 grams of cheese each.
