Find the ratio of the gravitational force on the Moon due to the Earth to the gravitational force on the Moon due to the Sun. (The mass of the Earth is 5.97 1024 kg, the mass of the Moon is 7.36 1022 kg, the mass of the Sun is 1.99 1030 kg, and the average Earth-Moon distance is 385,000 km, and the average distance between the Earth and the Sun is 1.50 1011 km.)

ForcemoonEarth=GMeMm/(dEM)^2

ForceEarthSun= GMeMs/(dES)^2

ratio= Mm/Ms * (DES/DEM)^2

So what in the world is hard about that?
