I have a problem that I've been working on FOREVER but can't figure out how to do.(adsbygoogle = window.adsbygoogle || []).push({});

Lunar Gravity at the Moon's surface is only 1/6 as strong as what we experience on Earth. Since the diameter of the Moon is about 1/4 as large as the Earth's, the lunar mass is about :

a) 3 X 10^-3 times the Earth's mass

b) 1 X 10^-2 times the earth's mass

c) 3/8 of the earth's mass

d) 1/3 of the earth's mass

e) 3 times the earth's mass

I'm just completely stuck (and very new to the physics thing!!).
