Complexity=30, Mode=reduce

In the first set of fraction answer boxes, put in the numerator and denominator expressed in terms of their prime factors. In the second set of fraction answer boxes, take out common factors and put the remaining factors. For the last set of answer boxes, multiply back out the factors to end up with the final reduced fraction.
i.e. 25/70 = (5^2)/(2 * 5 * 7) = 5/(2 * 7) = 5/14
