Explanation:
If the girl has a mass of 40 kg on Earth she will have the same mass on the Moon. But, on a scale on Earth the 40 kg mass will weigh about 88 pounds. On the Moon she would weight about 14.7 lbs because the gravity there is 1/6 that on the surface of the Earth. First, kilograms are a measure of mass, not weight.
