Question

People in England measure weights in units called stones. One pound equals 1/14 of a stone. If a cat weighs 3/4 stone, how many pounds does it weigh?

Answer 1

1 pound = 1/14 stone [multiply by 14] 14 pounds = 1 stone [multiply by 3] 42 pounds = 3 stone [divide by 4] 42 / 4 pounds = 3/4 stone [simplify] 21 /2 = 10.5 pounds = 3/4 stone
