The question is: The standard unit of measurement of force is the newton (N). It is the force needed to accelerate a mass of 1kg at 1 m/s^2 . On Earth's surface, a mass of 1 kg requires a force of 9.8 N to counteract the acceleration due to gravity of 9.8 m/s^2 downward. Multiplying the mass by this acceleration gives the weight. On the moon, the acceleration due to gravity is 1.63 m/s^2.

part c) When a certain object is floating in water on Earth, 75% of it is submerged. If water were found on the moon, and the same object were floating in i, how much of it would be submerged?

What I did was a ratio between the acceleration due to gravity of earth and the acceleration due to gravity of the moon and multiplied what was given to get an answer. However, the answer is 75% and I am not sure why. Can someone help explain? Any help would be appreciated.
