Your weight on the Moon is relative to your weight on Earth. Neil Armstrong weighed 360 lbs. In his moon gear while on the Earth, but on the Moon he only weighed 60 lbs. How much would a 150 lb person weigh on the moon?

Set up a ratio of Neil Armstrong's weight before over his after to the other persons weight before and after:

360 / 60 = 150 / X

Cross multiply:

360x = 150 * 60

360x = 9000

Divide both sides by 360:

x = 9000 / 360

x = 25

A 150 pound person would weigh 25 pounds on the moon.
