The weight of an object on the moon is directly proportional to its weight on Earth. Given that a 123 lb person weighs 24.6 lb on the moon, we can find the proportionality constant by dividing the moon weight by the Earth weight: 24.6 lb / 123 lb = 0.2. To find the weight of a 186-lb person on the moon, we multiply their Earth weight by this constant: 186 lb * 0.2 = 37.2 lb.
