What S 15 Of 48

Unpacking the Calculation: What's 15% of $48?

This article aims to comprehensively explain how to calculate 15% of $48, breaking down the process into easily digestible steps. We will explore various methods, from simple arithmetic to leveraging the power of calculators, and discuss the practical applications of such percentage calculations in everyday life. Understanding percentages is a crucial skill, applicable across numerous fields, from finance and budgeting to sales and discounts.

Method 1: Converting Percentage to Decimal

The most straightforward approach involves converting the percentage into its decimal equivalent before performing the multiplication. To convert a percentage to a decimal, we divide the percentage by 100.

Step 1: Convert 15% to a decimal:

15% ÷ 100 = 0.15

Step 2: Multiply the decimal by the total amount:

0.15 $48 = $7.20

Therefore, 15% of $48 is $7.20. This method is particularly useful when working with larger numbers or more complex percentage calculations. For instance, if you were calculating 3.75% of $1200, converting 3.75% to 0.0375 and then multiplying by $1200 would be significantly easier than using alternative methods.

Method 2: Using Fractions

Percentages can also be expressed as fractions. 15% represents 15 out of 100, which simplifies to the fraction 3/20.

Step 1: Express 15% as a fraction:

15% = 15/100 = 3/20

Step 2: Multiply the fraction by the total amount:

(3/20) $48 = (3 $48) / 20 = $144 / 20 = $7.20

This method is helpful for visualizing the proportion and can be beneficial when dealing with percentages that have convenient fractional equivalents. For instance, 25% is easily represented as ¼, simplifying the calculation. However, for percentages like 17%, the fractional equivalent becomes less practical.

Method 3: Using a Calculator

Calculators offer the quickest and most convenient method for calculating percentages, especially for more complicated calculations.

Step 1: Enter the total amount:

Input 48

Step 2: Multiply by the percentage:

Press the multiplication button () and enter 15. Then press the % button.

The calculator will automatically perform the calculation and display the result: $7.20. Modern calculators often have dedicated percentage buttons, simplifying the process significantly. This method is ideal for speed and accuracy, particularly when dealing with multiple percentage calculations or intricate financial computations.

Real-World Applications

Understanding how to calculate percentages is vital in many aspects of life. For example:

Sales and Discounts: A store offers a 15% discount on an item priced at $48. The discount amount is calculated as 15% of $48, which is $7.20. The final price would be $48 - $7.20 = $40.80.
Tips and Gratuities: Calculating a 15% tip on a $48 meal is the same calculation; 15% of $48 is $7.20.
Taxes: If a 15% sales tax is applied to a $48 purchase, the tax amount would be $7.20, resulting in a total cost of $55.20.
Investment Returns: If an investment of $48 earns a 15% return, the profit would be $7.20.

Conclusion

Calculating 15% of $48 consistently yields a result of $7.20 regardless of the method used. Choosing the most appropriate method depends on personal preference, the complexity of the calculation, and the tools available. Understanding percentage calculations is a fundamental skill applicable across numerous financial and everyday situations. Mastering these calculations will improve your ability to manage your finances, understand sales, and navigate everyday transactions with greater confidence.
