To divide by a fraction, multiply by its reciprocal. In this instance, 5/8 / 1/4 = 5/8 x 4 = 20/8 or 2 1/2.
3/4 x 4/5 = 12/20 = 6/10 = 3/5 or three fifthsNotice that the fours cancel out. Think about writing it as:3 x (1/4) x 4 x (1/5) = 3 x [(1/4) x 4] x (1/5) = 3 x [1] x (1/5) = 3 x (1/5) = 3/5.
The answer is 4/5 (dividing by one-half is multiplying by two). (2/5) divided by (1/2) = 2/5 x 2/1 = 4/5
