Chapter 7.2, Problem 65S

To determine

Calculate following proportion

  $\frac{m}{10}=\frac{4.2}{100}$

Answer to Problem 65S

For $\frac{m}{10}=\frac{4.2}{100}$ ,

Value of $m=0.42$

Explanation of Solution

Given:

  $\frac{m}{10}=\frac{4.2}{100}$

Calculations:

Here we have to calculate value of h,

  $\begin{array}{l}\frac{m}{10}=\frac{4.2}{100}\\ 100\times m=4.2\times 10\\ m=\frac{4.2\times 10}{100}\\ m=0.42\end{array}$

Conclusion:

Therefore, we are able to calculate value of m using simple percent proportion.
