Fraction Calculator
Fraction math with mixed numbers, simplified.
Accepts whole numbers, simple fractions like 3/4, and mixed numbers like 1 1/2. Use a leading minus sign for negative values.
How to use the Fraction Calculator
- 1 Enter the first fraction — a simple fraction like 3/4, a mixed number like 1 1/2, or a whole number.
- 2 Choose an operation: add, subtract, multiply or divide.
- 3 Enter the second fraction and read the simplified result, mixed-number form and decimal equivalent.
Examples
- ▸ 1 1/2 + 2/3 = 13/6 = 2 1/6 ≈ 2.1667.
- ▸ 3/4 ÷ 1/2 = 3/2 = 1 1/2 = 1.5.
Frequently asked questions
How do I add or subtract fractions with different denominators?
Convert both fractions to a common denominator by cross-multiplying, then add or subtract the numerators. This tool does that automatically and simplifies the result.
How do I divide fractions?
Multiply the first fraction by the reciprocal (flip) of the second. For example, 3/4 ÷ 1/2 becomes 3/4 × 2/1 = 6/4, which simplifies to 3/2.
How are mixed numbers handled?
A mixed number like 1 1/2 is converted to an improper fraction (3/2) internally, and the final result is converted back to mixed-number form for you.
How is a fraction simplified?
The numerator and denominator are both divided by their greatest common divisor (GCD), so 6/4 reduces to 3/2 — the smallest equivalent whole-number fraction.
