Understanding the Basics
A fraction represents a part of a whole, while a percentage expresses a number as a fraction of 100. Converting a fraction to a percentage essentially means finding an equivalent fraction with a denominator of 100.
The Fraction to Percent Formula
The most common and versatile fraction to percent formula is:
Percentage = (Fraction × 100)%
This formula works for all types of fractions – proper, improper, and mixed.
Step-by-Step Conversion
- Write down the fraction: Identify the numerator (the top number) and the denominator (the bottom number).
- Divide the numerator by the denominator: This will give you a decimal.
- Multiply the decimal by 100: This shifts the decimal point two places to the right.
- Add the percentage symbol (%): This indicates that your answer is a percentage.
For example, let's convert the fraction 3/4 to a percentage:
- Fraction: 3/4
- Divide: 3 ÷ 4 = 0.75
- Multiply: 0.75 × 100 = 75
- Add the symbol: 75%
Therefore, 3/4 is equal to 75%.
Alternative Method: Finding an Equivalent Fraction with a Denominator of 100
If the denominator of your fraction is a factor of 100 (e.g., 2, 4, 5, 10, 20, 25, 50), you can convert the fraction to a percentage by creating an equivalent fraction with a denominator of 100.
For instance, let's convert 7/20 to a percentage:
- What to multiply 20 by to get 100? Answer: 5
- Multiply the numerator and denominator by 5: (7 × 5) / (20 × 5) = 35/100
- Therefore, 7/20 is equal to 35%.
Real-World Applications
- Discounts: Calculating discounts in stores (e.g., "25% off" is the same as "1/4 off").
- Test Scores: Understanding your score on a test (e.g., 45 out of 50 correct is 90%).
- Financial Calculations: Calculating interest rates, investment returns, or loan payments.
- Data Analysis: Interpreting data presented as percentages in reports and articles.
