To determine

To solve : the proportion $\frac{5}{12}=\frac{x}{36}$

Answer to Problem 8CT

The solution of the proportion $\frac{5}{12}=\frac{x}{36}$ is $x=15$

Explanation of Solution

Given information :

Consider, the proportion

  $\frac{5}{12}=\frac{x}{36}$

Calculation:

Therefore, the solution of proportion is

  $\begin{array}{l}\frac{5}{12}=\frac{x}{36}\\ 36\cdot 5=x\cdot 12\left[\text{cross product property}\right]\\ 180=12x\left[\text{multiply}\right]\\ 15=x\left[\text{divide both side with 12}\right]\end{array}$

Hence,The solution of the proportion $\frac{5}{12}=\frac{x}{36}$ is $x=15$
