A person who weighs 100 pounds on Earth weighs 1.16lb on the moon. How much would a 185-pound astronaut weigh on the moon? Use an equation to explain how you know.

Answer 1

You would use a ratio for this problem. If x = the unknown

Then,

1.16 moon lbs/100 earth lbs = x moon lbs/185 earth lbs

or x = (1.16)(185)/(100) = 2.146 moon lbs
