To determine

To solve: the given proportion.

Answer to Problem 39S

Hence, the value of n is 6.

Explanation of Solution

Given:

  $\frac{n}{20}=\frac{15}{50}$

Calculation:

Consider the equation $\frac{n}{20}=\frac{15}{50}$

The objective is to find the value of n.

Simplify the equation as follows:

  $\begin{array}{l}\frac{n}{20}=\frac{15}{50}\\ n\cdot 50=15.20Crossproduct\\ 50n=300Multiply\\ n=\frac{300}{50}Divide\\ n=6Simplify\end{array}$

Hence, the value of n is 6.

Conclusion:

Hence, the value of n is 6.
