Ur welcome!

Answer 2

let's say those numbers are "a" and "b"

so.. we know that a/b are 7/5, whatever "a" and "b" may be

and we also know that their sum is 36, or a + b = 36

thus
`\bf \begin{cases} \cfrac{a}{b}=\cfrac{7}{5}\implies \boxed{a}=\cfrac{7b}{5}\\\\ a+b=36\\ ----------\\ \boxed{\cfrac{7b}{5}}+b=36 \end{cases}`

solve for "b", to see what "b" is

what's "a"? well
`\bf a=\cfrac{7b}{5}`
