HELP THIS IS MY LAST QUESTION ! <3
The weight of an object on the moon varies directly as its weight on earth. A person who weights 27.4 lb on the moon weights 164.4 lbs on earth. How many pounds would be a 270 lb person weigh on the moon?

Answer 1

Answer:

45 lb

Step-by-step explanation:

You can simple use unitary methods.

It is a simple visualization:

27.4 on moon = 164.4 on earth

(27.4/164.4) on moon = 1 on earth

270(27.4/164.4) on moon = 270 on earth

45 on moon = 270 on earth

Or, use, unitary method,

=> 164.4/27.4 = 270/x

=> x = (270 × 27.4)/164.4

=> x = 45

Or, use the concept "weight becomes 1/6 of the real one(of that on earth)".

270 lb on moon = 270/6 = 45 lb
