So the problem asks us to find the fraction of your class that plays the saxophone. To find this, all you need to do is divide 2/5 by 1/4. We need to do this because we are basically taking 1/4 of 2/5. When we do this operation, we get 8/5, which is 1 3/5 in mixed fraction form. Hence, the solution to your question is 8/5 or 1 3/5 of the fraction of students in the band play the saxophone. Hope this helps!
