Question

The ratio of an object's weight on Earth to its weight on Neptune is 5 : 7. How much would a person who weighs 150 pounds on Earth weigh on Neptune?

Answer 1

you got a proportion here..
5/7 = 150/x --- (weight of 5 (earth) to 7 (neptune) = 150 (earth) to x (neptune)
cross multiply
(5)(x) = (7)(150)
5x = 1050 -- divide both sides by 5
x = 210

check..
5/7 = 150/210
cr0ss multiply
(5)(210) = (7)(150)
1050 = 1050 (correct)

if the weight on earth is 150, then the weight on neptune is 210
