The Problem

Amys dog weighs 5 times as much as her hamster. Together they weigh 20 pounds. How much does the dog weigh?

Answer provided by our tutors

let 'x' represent the weight of her hamster, then '5x' represents the weight of her dog

20 = x + 5x

x = 20/6 = 3 1/3

20 - 3 1/3 = 16 2/3

Amy's hamster weighs 3 1/3 pounds, her dog weight 16 2/3 pounds
