To determine

To solve : the proportion $\frac{b}{54}=\frac{12}{18}$

Answer to Problem 10CT

The solution of the proportion $\frac{b}{54}=\frac{12}{18}$ is $b=36$

Explanation of Solution

Given information :

Consider, the proportion

  $\frac{b}{54}=\frac{12}{18}$

Calculation:

Therefore, the solution of proportion is

  $\begin{array}{l}\frac{b}{54}=\frac{12}{18}\\ b\cdot 18=12\cdot 54\left[\text{cross product property}\right]\\ 18b=\text{648 }\left[\text{multiply}\right]\\ b=36\left[\text{divide both side with 18}\right]\end{array}$

Hence,The solution of the proportion $\frac{b}{54}=\frac{12}{18}$ is $b=36$
