An object's weight on the moon, M varies directly as its weight on Earth, E.
A person who weights 55 kilograms on Earth weighs 8.8 kilograms on the moon.
What is the moon weight of a person who weights 90 kilograms on Earth?
Is it 14.4 Kg?
:
Solve this as a ratio equation, Let w = his weight on the moon
w%2F8.8 = 90%2F55
Cross multiply
55w = 8.8 * 90
55w = 792
w = 792%2F55
w = 14.4 kg on the moon
