In 5 min, Peter completed 2 math problems. Yvonne says he did 3/5 of a problem each minute. Is she correct? Explain. Sorry I really didn't get my math homework.

for ms.sue please answer 
Ms. Sue,
Let's add to see if Yvonne is right.
3/5 in 1 minute
3/5 + 3/5 + 3/5 + 3/5 + 3/5 = 15/5 = 3 math problems in five minutes.
Yvonne is wrong.
Let's try adding 2/5
2/5 + 2/5 + 2/5 + 2/5 + 2/5 = 10/5 = 2 math problems in 5 minutes
