Worked Example

Let's walk through a practical example to solidify your understanding. Suppose you want to calculate 15% of 24,000:

Start with the original number: 24,000.
Convert 15% to a decimal: 15 ÷ 100 = 0.15.
Multiply the decimal by the original number: 0.15 × 24,000 = 3,600.
The result is 3,600, meaning 15% of 24,000 is 3,600.

This example demonstrates how to apply the percentage formula in a real-world context. The result shows that 15% of 24,000 is 3,600.

Common Mistakes

When calculating percentages, several common mistakes can lead to incorrect results. Here are some pitfalls to avoid:

Forgetting to convert the percentage to a decimal: Many people mistakenly multiply the percentage directly by the original number, leading to incorrect results. Always remember to divide the percentage by 100 first.
Rounding too early: Rounding intermediate results can lead to significant errors. It's best to keep as many decimal places as possible during calculations and round only the final result.
Misplacing the decimal point: When converting percentages to decimals, ensure you place the decimal point correctly. For example, 15% should be 0.15, not 0.015 or 1.5.

By being aware of these common mistakes, you can ensure accurate percentage calculations and avoid errors in your work.
