Question

A person who weighs 150 pounds weighs 25 pounds on the Moon. Suppose an object weighs 80 pounds on the Moon. What’s the objects weight on the Earth?

Answer 1

480 pounds

Explanation:

we times for objects on earth and divide for objects on the moon by the same number

150

`150 / x = 25`

150/-25=-x

-6/-1= -x/-1

6=x

`150 / 6 = 25`

so when in object is on earth you multiple by x Wich 6

`80 * 6 = 480`

you can also cross multiply

Answer 2

480 lbs

Explanation:

First, find the ratio of weight on the moon to weight on the earth. I will put the two known values in a fraction like this:

`(25)/(150)`

Now, I can create a proportion, making sure to keep the same types of measurements in the numerator and denominator. I will use w for the unknown weight on earth.

`(25)/(150)=(80)/(m)`

Now, I will simplify the fractions as much as I can.

`(1)/(6)=(80)/(m)`

Now, I can see a correlation. 1 times 80 is 80, so 6 times 80 is m. Simplified, here is the answer!

`6*80=m\\480=m\\m=480`
