Percentage = (5 ÷ 8) × 100
Percentage = 0.625 × 100
Percentage = 62.5%
Example 3: Convert 7/10 to a percentage
Percentage = (7 ÷ 10) × 100
Percentage = 0.7 × 100
Percentage = 70%

Understanding Fractions and Percentages
A fraction represents a part of a whole, expressed as one number (numerator) divided by another (denominator). A percentage is another way to express a part of a whole, but it's always out of 100. Converting between these two forms is a common mathematical operation used in many real-world situations.

Tips for Using Fractions and Percentages
- Remember that percentages are just fractions with 100 as the denominator
- To convert a percentage back to a fraction, divide by 100 and simplify
- Improper fractions (numerator larger than denominator) convert to percentages greater than 100%
- Mixed numbers should be converted to improper fractions first
- The calculator handles decimal results automatically
Frequently Asked Questions
Can I convert improper fractions?
Yes! Improper fractions (where the numerator is larger than the denominator) will give you percentages greater than 100%. For example, 5/4 = 125%.
How do I convert mixed numbers?
First, convert the mixed number to an improper fraction, then use our calculator. For example, 2 1/2 becomes 5/2, which equals 250%.
Why do I get decimal percentages?
Some fractions don't convert to whole number percentages. For example, 1/3 = 33.33%. This is normal and the calculator shows accurate decimal results.
Can I enter decimal numbers?
Yes! The calculator accepts decimal numbers in both the numerator and denominator fields for maximum flexibility.
What if my denominator is zero?
Division by zero is mathematically undefined. The calculator will alert you if you try to use zero as the denominator.
