Question 963515

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[m]}}}, the weight of an object on Earth {{{w[e]}}}

then we have:

{{{w[m]:w[e]=0.4:1}}}

a) How much will a {{{6}}} ton rocket weigh on Mars?

if {{{w[e]=6ton}}}, then
{{{w[m]:6ton=0.4:1}}}
{{{w[m]*1=0.4*6ton}}}
{{{w[m]=2.4ton}}}

b) How much will a {{{159lb}}} astronaut weigh on Mars?

if {{{w[e]=159lb}}}, then
{{{w[m]:159lb=0.4:1}}}
{{{w[m]*1=0.4*159lb}}}
{{{w[m]=63.6lb}}}
