So, you want to know what percentage 5 out of 15 represents? This is a common question with straightforward calculations. This article will not only answer that question but also equip you with the knowledge to tackle similar percentage problems in the future. Understanding percentages is crucial in many aspects of life, from calculating discounts to understanding financial reports.

Understanding Percentages:

A percentage is a fraction or ratio expressed as a number out of 100. The symbol "%" signifies "percent" or "out of 100". Calculating percentages involves finding the proportion of one number relative to another.

Calculating the Percentage:

There are two main ways to calculate what percentage 5 out of 15 is:

Method 1: Using a Fraction and Decimal Conversion

1. Express as a fraction: Write the numbers as a fraction: 5/15
2. Simplify the fraction: Reduce the fraction to its simplest form by dividing both numerator and denominator by their greatest common divisor (GCD), which is 5 in this case. This simplifies to 1/3.
3. Convert to a decimal: Divide the numerator (1) by the denominator (3): 1 ÷ 3 = 0.3333... (This is a repeating decimal)
4. Convert to a percentage: Multiply the decimal by 100: 0.3333... x 100 ≈ 33.33%

Therefore, 5 out of 15 is approximately 33.33%.

Method 2: Using a Proportion

This method is useful for understanding the underlying concept.

1. Set up a proportion: We want to find x, where x/100 represents the percentage. Our proportion is: 5/15 = x/100
2. Cross-multiply: Multiply 5 by 100 and 15 by x: 500 = 15x
3. Solve for x: Divide both sides by 15: x = 500/15 ≈ 33.33
4. Express as a percentage: x is approximately 33.33%, the same result as Method 1.

Practical Applications:

Understanding percentage calculations has many real-world applications:

• Sales and discounts: Calculating discounts offered during sales events.
• Financial analysis: Interpreting financial statements and understanding profit margins.
