8 Out Of 24 Is What Percent

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

Calculating percentages is a fundamental skill with wide-ranging applications in everyday life, from understanding sales discounts to analyzing financial data. This comprehensive guide will delve into how to calculate "8 out of 24 is what percent," exploring the underlying principles, offering multiple calculation methods, and highlighting practical applications. We'll also touch upon related percentage problems and provide tips for mastering percentage calculations.

Understanding the Fundamentals of Percentages

Before we tackle the specific problem, let's establish a solid understanding of percentages. A percentage represents a fraction of 100. The term "percent" literally means "per hundred." Therefore, 50% means 50 out of 100, or 50/100, which simplifies to 1/2.

The key to understanding percentages is recognizing that they represent a proportion or ratio. The question "8 out of 24 is what percent?" can be rephrased as: "What percentage of 24 is 8?" This phrasing helps to clarify the relationship between the parts and the whole.

Method 1: Using the Proportion Method

This is arguably the most straightforward method for calculating percentages. We set up a proportion:

• Part/Whole = Percentage/100

In our case:

• 8/24 = x/100

To solve for 'x' (the percentage), we cross-multiply:

• 8 * 100 = 24 * x
• 800 = 24x

Now, divide both sides by 24:

• x = 800 / 24
• x = 33.33% (approximately)

Therefore, 8 out of 24 is approximately 33.33%.

Method 2: Converting the Fraction to a Decimal

Another effective method involves converting the fraction 8/24 to a decimal and then multiplying by 100 to express it as a percentage.

First, simplify the fraction:

• 8/24 = 1/3

Next, convert the fraction to a decimal by dividing the numerator (1) by the denominator (3):

• 1 ÷ 3 = 0.3333...

Finally, multiply the decimal by 100 to obtain the percentage:

• 0.3333... * 100 = 33.33% (approximately)

This method yields the same result as the proportion method.

Method 3: Using a Calculator

Most calculators have a percentage function. Simply enter 8 ÷ 24 and then multiply the result by 100. The calculator will directly give you the percentage. This is a quick and efficient method, particularly for more complex percentage calculations.

Understanding the Significance of the Result

The result, approximately 33.33%, signifies that 8 represents one-third (1/3) of 24. This percentage can be used in various contexts, from determining the percentage of students who passed an exam to calculating the proportion of a budget allocated to a specific expense.

Practical Applications of Percentage Calculations
