(1/4) *(4/5) = (4/20) = (1/5)

Since it is a multiplication operation, a common denominator is not required. Multiply the numerators together ( 1 *4 =4), and multiply the numberators together ( 4 *5 = 20) . You`d want the final answers to be in simplest form.. so from (4/20), it will turn into (1/5), after dividing the final answer by the highest common number, which is four in this case.
