<PRE><B>Question 1095089</B>
-----------------------------------------------------------------------------
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-(1/5)220-(1/4)220}}}

{{{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?</PRE>
