Hi so have you heard of KFC? It stands for keep flip change. You use it when adding or subtracting or when you're dividing fractions. So you keep the first part of the problem the same; you flip the sign of the second part, and change the sign of the third part. So -23.9- -9.3 becomes -23.9 + +9.3. So take away 9.3 from 23.9 and get 14.6. Whenever you add a positive to a negative like we do here, the answer will become a smaller negative number if the positive number is "smaller" than the negative number.

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!
