Question

Sam has a collection of stamps. He adds 4/5 of a new set of stamps to his collection. If his collection initially had 3/5 of the new set, what fraction of the new set does Sam have?

Answer 1

7/5

Explanation:

If he starts with 3/5 of the new set, then he begins with 3/5

After adding 4/5 of the new set, you add his current stamps with the new stamps, 3/5 + 4/5 , which results in 7/5
