Question

(1)/(2) of the advanced math class tried out for the math competition. (3)/(4) of this group qualified for the competition. What fraction of the original math class qualified for the competition? (A) (3)/(8) (B) (2)/(3) (c) 1(1)/(4) (D) (1)/(4)

Answer 1

We multiply 1/2 of the math class with 3/4 of the group that qualified and get (1*3)/(2*4) = 3/8. So, 3/8 of the math class qualifies for the math competition.
