To determine

To describe: two different ways used to find 20% of 60

Answer to Problem 47HP

Two different ways is described.

Explanation of Solution

Calculation:

The expression is 20% of 60.

First way:

  $\begin{array}{l}20\%\text{of 60}=\frac{2}{10}\text{'}60\text{Think}:20\%=\frac{2}{10}\\ =12\end{array}$

Second way:

  $\begin{array}{l}20\%=\frac{20}{100}\\ =\frac{1}{5}\\ =0.2\end{array}$

Now, Multiply $0.2\text{'}$ with 60.

  $20\%60=12$

Hence, $20\%\text{of}60=12$ .

Conclusion:

Hence, two different ways is described.
