Question

What is the value of x? 20/72=x/360

Answer 1

`\begin{gathered} (20)/(72)=(x)/(360) \\ \text{You simplify the left hand side of the equation},\text{ i.e divide by 4} \\ (5)/(18)=(x)/(360) \\ \text{You cross multiply and you now have} \\ 5*360=18x \\ \text{Divide both sides by 18 which is the coefficient of x} \\ 5*20=x \\ 100=x \end{gathered}`

The value of x = 100
