Question

A neighbor pays you and two friends $90 to paint her garage. You divide the money three ways in the ratio 2:3:5.

Answer 1

3x + 5x +7x = 90
15x = 90
x=6

Now, substitute that back into the original equation I showed you to find the three parts.

3(6) + 5(6) + 7(6) = 90
18 + 30 + 42 = 90
Your 3 parts are 18, 30, and 42. Hope this helped! :D

Answer 2

First friend gets $18, second friend gets $27, third friend gets $45

Explanation:

The ratio means that each person get different quantity.

The total amount must be divided between the 3 persons in the following way

First person gets 2 parts

Second person gets 3 parts

Third person gets 5 parts

If we add all parts, we get 10 parts,if we divide the total payment we get how much is each part, in this case $90 / 10 , so $9

Each part is $9. To get how much will get each friend , we multiple the quantity of parts by the value of them.

First person gets 2 parts, that means $18

Second person gets 3 parts that means $27

Third person gets 5 parts that means $45
