Joey gave away 1/2 of his race car collection. of what he has left, he sold 1/8 of the cars to his friend. what fraction of the collection was sold to his friend?

The answer is 1/16 of his car collection.

Step-by-step explanation:

Because he had already given half (1/2) of his collection away, every fraction of his current stash is half of what it would be originally. Therefore, 1/8 would be 1/16 because 8 is half of 16. Hope that all makes sense! :D
