Craig has a collection of 220 marbles. He let his friend have 1/4 of his
collection and sells 1/5 of his collection to a store. He takes 15 marbles home. How many does he have left?

Should this part be the answer to the question?
---
He takes 15 marbles home.

Does this fit the description?
220-%281%2F5%29220-%281%2F4%29220
220-44-55
121
So he has 121 marbles left but he takes 15 marbles home. Why should these be different? What happened to the other 106 marbles?
