Vince weighs 160 pounds, and his friend Nadir weighs 140 pounds. Nadir calculated that his weight on another planet would be about 56 lb. Approximately what would Vince weigh on the other planet?

Nadir’s weight changes from 140 lb to 56 lb, so the planet’s gravity makes weights 56 ÷ 140 = 0.4 times their Earth weights. Vince would weigh 160 × 0.4 = 64 lb, so the correct choice is 64 lb.
