A walker's speed, v, is proportional to the ratio of his leg length, L, and the period of the repeating motion of his legs, T, that is, v ∝ L/T. If the period is measured to be proportional to Lp, where p = 3/4, what power of L must the speed be proportional to? Enter your answer as a fraction (in lowest terms), first the numerator, then the denominator.
