Finding 10% of a number is a fundamental skill in math, useful in many everyday situations – from calculating discounts to understanding statistics. Let's explore how to calculate 10% of 240, and then look at broader applications of percentage calculations.

Understanding Percentages

A percentage is a fraction or ratio expressed as a number out of 100. The symbol "%" represents "per cent," meaning "out of one hundred." Therefore, 10% means 10 out of 100, or 10/100, which simplifies to 1/10.

Calculating 10% of 240: The Easy Way

The simplest way to find 10% of a number is to divide that number by 10. Since 10% is equivalent to 1/10, we can simply move the decimal point one place to the left.

Therefore, 10% of 240 is:

240 ÷ 10 = 24

So, 10% of 240 is 24.

Calculating Other Percentages of 240

Understanding how to find 10% makes calculating other percentages much easier. For example:

20% of 240: Since 20% is double 10%, we can simply double the result we already obtained: 24 x 2 = 48
5% of 240: 5% is half of 10%, so we can halve our initial result: 24 ÷ 2 = 12
15% of 240: We can add 10% and 5%: 24 + 12 = 36
25% of 240: 25% is a quarter, meaning we divide by 4: 240 ÷ 4 = 60

The General Formula for Calculating Percentages

For any percentage calculation, you can use this formula:

(Percentage/100) * Number = Result

For example, to find 15% of 240:

(15/100) * 240 = 36

Practical Applications of Percentage Calculations

Percentage calculations are used extensively in many real-world scenarios, including:

Sales and Discounts: Calculating the discount amount on sale items.
Taxes: Determining the amount of tax payable on purchases.
Tips and Gratuities: Figuring out the appropriate tip amount in restaurants.
Interest Rates: Calculating interest earned on savings accounts or paid on loans.
Statistics and Data Analysis: Representing data as percentages for better understanding.

Conclusion

Calculating 10% of 240, or any percentage for that matter, is a straightforward process. Understanding this fundamental concept provides a strong foundation for tackling more complex percentage problems in various fields. Remember the simple method of dividing by 10 for 10%, and you can easily derive other percentages from there! Mastering percentages is a valuable skill that enhances your numeracy and problem-solving abilities.
