What Percentage is 3 out of 15? A Simple Guide

You might encounter scenarios where you need to express a part of a whole as a percentage. For example, if you have 3 correct answers out of 15 questions on a test, you might want to know what percentage of questions you answered correctly.

Let's break down how to calculate this:

Understanding Percentages

A percentage represents a part of a whole, expressed as a fraction of 100. The symbol "%" is used to denote percentage.

Calculating the Percentage

1. Set up a fraction: The fraction representing the part over the whole is 3/15.
2. Convert the fraction to a decimal: Divide the numerator (3) by the denominator (15), resulting in 0.2.
3. Multiply the decimal by 100: 0.2 x 100 = 20%.

Therefore, 3 out of 15 is equal to 20%.

Practical Applications

This calculation has many applications, including:

• Calculating test scores: As mentioned earlier, determining the percentage of correct answers on a test.
• Analyzing sales figures: Determining the percentage of sales achieved against a target.
• Budgeting: Calculating what percentage of your income is spent on different categories.
• Evaluating investment returns: Determining the percentage growth of an investment.

Further Exploration

You can use online calculators or spreadsheets to quickly calculate percentages. Many of these tools will also allow you to reverse the calculation, finding the part if you know the percentage and the whole.
