What is Percentage?

Percentage is a way to express a value as a fraction of 100. It is denoted by the symbol $\%$. For example, $5\%$ means 5 out of 100, or $\frac{5}{100}$.

Calculating Percentage

To calculate a percentage, we need to multiply the value by the percentage as a decimal. In this case, we need to find $5\%$ of 240.

Step 1: Convert the percentage to a decimal

To convert a percentage to a decimal, we divide by 100. So, $5\%$ as a decimal is $\frac{5}{100} = 0.05$.

Step 2: Multiply the value by the decimal

Now, we multiply 240 by 0.05 to find $5\%$ of 240.

Calculation

$5\%$ of 240 = 240 x 0.05 = 12

Conclusion

Therefore, $5\%$ of 240 is 12.
