Quizplus · Accepted Answer

The weight on the Moon is calculated as a fraction of the weight on Earth. Given that a 195 lb person weighs 39 lb on the Moon, we can find the ratio of Moon weight to Earth weight: 39/195 = 0.2. To find the weight of a 115-lb person on the Moon, multiply their Earth weight by this ratio: 115 * 0.2 = 23 lb.
