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

I will do one question only as your guide.
Set up a proportion.
Mars to Earth is written Mars : Earth or Mars/Earth.
9/25 = x/120 pounds
Cross-multiply and solve for x.
9 times 120 = 25 times x
1080 = 25x
Divide BOTH sides by 25 to find x.
1080/25 = x
43.2 pounds = x
A person who is 120 pounds on Earth, is 43.2 pounds on Mars.
Solve the other question the same way.

x/120=9/25 so x= 120*9/25=43.2 pounds

1. Set up a ratio and cross multiply.
9/25= x/120
120x9=25x
x=43.2

1- 9/25 * 120 = 43.2 lbs
2- 1.6/2 = x/8.5
x = 8.5 * 1.6/2 = 6.8m
