15-1 out of 7 = 8 / 7



What's the product of five out of seven and his reciprocal


The product of five out of seven and his reciprocal is one



What is the product of the sum of 1 / 5 and 1 / 3 multiplied by the reciprocal of 1 / 15?


(1 / 5 + 1 / 3) times 15 (because the reciprocal of 1 / 15 is 15)
= 1 / 5 times 15 + 1 / 3 times 15
