The ratio of the weight of an object on Mars to its weight on Earth is 9 to 25. If a person weighs 120 pounds on Earth, how much would the person weigh on Mars?

Wm = 43.2 pounds

Step-by-step explanation:

If the ratio of the weight of an object on Mars to its weight on Earth is 9 to 25, this means that what on Mars weighs 9 units on earth weighs 25 units, therefore:

Data

ratio = 9/25

Weight on Mars (Wm) = ?

Weight on Earth (We) = 120 pound

Wm = (9/25) * 120 pound = 43.2 pounds

Since the ratio of the object on Mars to Earth is 9:25 (or can be written as 9/25), it is indicated already that the person whom is 120 pounds, weighs far less on mars. Therefore, to figure out their weight, multiply the given ratio, 9/25, to 120, which will give you the answer of 43.2 pounds.
