- Your friend, Misha, solved the problem above by first setting up the proportion:\(\dfrac{x}{20}= \dfrac{5}{15}\) and found that \(x = 6\dfrac{2}{3}’\). Your other friend, Jon, set up the proportion: \(\dfrac{5}{15}=\dfrac{x}{x+20}\) and found that \(x = 10’\). Who is correct and why?
- Think of another application, create a problem around it and solve it.
