Chapter 6, Problem 15CT

To determine

To solve:the proportion $\frac{8}{w}=\frac{1.2}{3}$

Answer to Problem 15CT

The solution of the proportion $\frac{8}{w}=\frac{1.2}{3}$ is $w=20$

Explanation of Solution

Given information :

Consider, the proportion

  $\frac{8}{w}=\frac{1.2}{3}$

Calculation:

Therefore, the solution of proportion is

  $\begin{array}{l}\frac{8}{w}=\frac{1.2}{3}\\ 8\cdot 3=w\cdot 1.2\left[\text{cross product property}\right]\\ 24=1.2w\left[\text{multiply}\right]\\ w=20\left[\text{divide both side with 1}\text{.2}\right]\end{array}$

Hence,The solution of the proportion $\frac{8}{w}=\frac{1.2}{3}$ is $w=20$
