The weight of an object on Earth is directly proportional to the weight of that same object on  the moon. A 200 lb astronaut would weigh 50 lb on the moon. How much would a 100 lb dog weigh on the moon?

Make a proportion 200 / 50 = 100 / x where x is the dog's weight on the moon.

x = 50*100/ 200 = 25 lb.

Answer: 25 lb
