(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Suppose that the ratio of the Moon's mass to the Earth's mass is given by 1.200E-2 and that the ratio of the Moon's radius to the Earth's radius is given by 2.740E-1. Calculate the ratio of an astronaut's Moon-weight to Earth-weight.

2. Relevant equations

Wmoon = mg

Wearth = mg

gmoon=

gearth= 9.81m/s^2

g= Gm/r^2

3. The attempt at a solution

Okay this seems like a very simple problem but the fact that they are giving me ratios in the problem for the mass and radius I am confused as to how to go about solving this.
