About Fraction Calculator
A complete fraction calculator: simplify fractions to lowest terms, perform arithmetic (add, subtract, multiply, divide), convert between fractions and decimals. Supports mixed numbers like 1 3/4.
How It Works
Enter fractions separated by operators (3/4 + 1/2) or a single fraction to simplify. The tool finds the LCD, performs the operation step by step, and simplifies the result. Mixed numbers are converted to improper fractions first.
Step by Step
- 1 Enter a fraction or expression (e.g., '3/4 + 1/2')
- 2 Select an operation: simplify, add, subtract, multiply, or divide
- 3 Click Calculate to see the step-by-step solution
Tips
- Use mixed number notation: 1 3/4 means one and three-quarters
- The tool shows the LCD (Least Common Denominator) for addition/subtraction
- Results are automatically simplified to lowest terms
- Convert decimals like 0.75 to fractions using the toFraction mode
Frequently Asked Questions
How do you add fractions with different denominators?
Find the LCD (Least Common Denominator), convert both fractions to equivalent fractions with that denominator, then add the numerators. Example: 1/3 + 1/4 → 4/12 + 3/12 = 7/12.
What is a mixed number?
A mixed number combines a whole number and a fraction, like 2 3/4. It equals the improper fraction 11/4 (2×4+3 = 11 over 4).
