Answer:
c) 2
Step-by-step explanation:
here you can use cross multiplication. that's where you turn the fraction into an equation. ( there's videos about it, I'm not very good at explaining )
so you can turn
![\frac{5}{x} = \frac{15}{x + 20}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7Bx%7D%20%3D%20%5Cfrac%7B15%7D%7Bx%20%2B%2020%7D)
into
5(x + 20) = 15x
5x + 100 = 15x
subtract 5x from both sides
100 = 10x
x = 10.
the value of x/5 would be 2, since 10/5 is 2.
