Calculating percentages is a fundamental skill with applications across various fields, from everyday budgeting to complex scientific analysis. Understanding how to convert fractions into percentages is key. This article will walk you through the process of determining what percentage 13 represents out of a total of 16, providing a clear, concise, and easy-to-understand method.

Understanding Percentages

A percentage is a way of expressing a number as a fraction of 100. For example, 50% means 50 out of 100, or 50/100, which simplifies to 1/2. The percentage symbol (%) is used to represent this fraction.

Calculating the Percentage: 13 out of 16

To find out what percentage 13 is out of 16, we follow these simple steps:

1. Form a Fraction: First, represent the problem as a fraction. In this case, the fraction is 13/16. This means 13 is the part, and 16 is the whole.

2. Convert the Fraction to a Decimal: Divide the numerator (13) by the denominator (16): 13 ÷ 16 = 0.8125

3. Convert the Decimal to a Percentage: Multiply the decimal by 100: 0.8125 × 100 = 81.25

Therefore, 13 out of 16 is 81.25%.

Alternative Method: Using Proportions

Another approach involves setting up a proportion:

• Let 'x' represent the percentage we're trying to find.
• We can set up the proportion: 13/16 = x/100

To solve for 'x', cross-multiply:

16x = 1300

Then, divide both sides by 16:

x = 1300/16 = 81.25

This confirms that 13 out of 16 is 81.25%.

Practical Applications and Further Exploration

Understanding percentage calculations is crucial in many real-world scenarios:

• Calculating grades: Determining your final grade in a class based on individual assignment scores.
• Financial analysis: Calculating interest rates, discounts, and profit margins.
• Data interpretation: Understanding statistical data presented in percentage form.
• Everyday life: Figuring out tips, sales tax, or the percentage of completion of a project.

This simple example demonstrates a core mathematical concept applicable in numerous situations. Practice with different numbers and problems to strengthen your understanding of percentage calculations. Experiment with converting other fractions to percentages to improve your proficiency. Mastering percentages opens up a wide range of problem-solving abilities.
