The ratio of the weight of an object on Mars to the weight of an object on Earth is 0.4 to 1.
let the weight of an object on Mars be w%5Bm%5D, the weight of an object on Earth w%5Be%5D
then we have:
w%5Bm%5D%3Aw%5Be%5D=0.4%3A1
a) How much will a 6 ton rocket weigh on Mars?
if w%5Be%5D=6ton, then
w%5Bm%5D%3A6ton=0.4%3A1
w%5Bm%5D%2A1=0.4%2A6ton
w%5Bm%5D=2.4ton
b) How much will a 159lb astronaut weigh on Mars?
if w%5Be%5D=159lb, then
w%5Bm%5D%3A159lb=0.4%3A1
w%5Bm%5D%2A1=0.4%2A159lb
w%5Bm%5D=63.6lb
