Question 602609: 5/8 of the students in Mr. Halls class got an A or a B. Four times as many students go an A than got a B. What fraction of Mr. Hall's class got an A?

Let x = # of students who got a B

x+4x = 5/8

5x = 5/8

x = (5/8)*(1/5)

x = 1/8

4x = 4*(1/8) = 4/8 = 1/2


So 1/2 of the class got an A
