Question

What are two numbers in the ratio 7:3 that have the difference of 20 between them?

Answer 1

The answer for

x=35

y=15

Explanation:

let the first number be x

" second number " be y

x:y=7:3

x-y=20

x=20+y

x:y=7:3

20+y/y=7/3

7y=3(20+y)

7y=60+3y

7y-3y=60

4y=60

divide both sides by 4

y=15

x=20+y

x=20+15

x=35
