Question 202777: The ratio of the weight of an object on Mars to the weight of that object on Earth is 0.4 to 1
a.) How much would a 12-ton rocket weigh on Mars?
b.) How much would a 120-lb astronaut weigh on Mars? Found 2 solutions by rfer, Earlsdon:Answer by rfer(16322) (Show Source):
You can put this solution on YOUR website! A) .4/x:1/12
cross multiply
x=.4*12
x=4.8 tons
----------------
B) .4/x:1/120
x=.4*120
x=48 lbs
You can put this solution on YOUR website! The ratio of the weight on Mars to the weight on earth is %.
So you would just multiply the object's earth-weight by 40% (or 0.4) to get the object's Mars-weight.
a) For the 12-ton rocket: tons.
b) For the astronaut: lbs.
