an object that weighs 10 lb on earth would weigh only 4lb on mars. If you weigh 95 lb on earth, how much would you weigh on mars

Answers

The weight of the object on mars when the weight on earth is 95 lb is 38 lb.

What are ratios?

We can determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio. Ratios can be divided into two groups. One is the part-to-whole ratio, and the other is the part-to-part ratio. The link between two distinct entities or groupings is depicted by the part-to-part ratio.

Given weight on earth = 10 lb

weight on mars = 4 lb

so weights are in ratio = 10/4

when weight on earth = 95 lb

then weight on mars be x

95/x

since both weights are of earth and mars then they are in proportion,

10/4 = 95/x

x = 95 x 4/10

x = 38 lb

Hence weight on mars is 38 lb.

#SPJ3

you need to find the unit rate.
10/4 will be 95/x so 4 divided by 10 equals 0.4
then you multiply 0.4 by 95 which equals 38
so you will weigh 38 pounds on mars since:
10/4=1/0.4 1/0.4=95/38
