15 Is What Percent Of 24

15 is What Percent of 24? A Comprehensive Guide to Percentage Calculations

Calculating percentages is a fundamental skill applicable across numerous fields, from everyday budgeting to complex financial analysis. Understanding how to determine what percentage one number represents of another is crucial for interpreting data, making informed decisions, and generally navigating the numerical world. This article delves deep into the question, "15 is what percent of 24?", providing a step-by-step solution, exploring various calculation methods, and offering practical applications to solidify your understanding of percentage calculations.

Understanding Percentages

Before diving into the specifics of our problem, let's solidify our understanding of percentages. A percentage is simply a fraction expressed as a part of 100. The symbol "%" signifies "per cent," meaning "out of 100." For example, 50% means 50 out of 100, which is equivalent to the fraction 50/100 or the decimal 0.5.

Method 1: The Formula Approach

The most straightforward method to solve "15 is what percent of 24?" involves a simple formula:

(Part / Whole) * 100 = Percentage

In our case:

• Part: 15 (the number we want to express as a percentage)
• Whole: 24 (the total number)

Let's plug these values into the formula:

(15 / 24) * 100 = 62.5%

Therefore, 15 is 62.5% of 24.

Method 2: Using Proportions

Another effective method uses proportions. We can set up a proportion to solve for the unknown percentage (x):

15/24 = x/100

To solve for x, we cross-multiply:

15 * 100 = 24 * x

1500 = 24x

x = 1500 / 24

x = 62.5

Therefore, x = 62.5%, confirming our previous result.

Method 3: Decimal Conversion

This method involves converting the fraction into a decimal and then multiplying by 100 to express it as a percentage.

1. Divide the part by the whole: 15 / 24 = 0.625
2. Multiply the decimal by 100: 0.625 * 100 = 62.5%

This method is concise and efficient, particularly when using a calculator.
