Calculadora de Frações Online Grátis
Add/subtract/multiply/divide with simplified result & mixed number
The Fraction Calculator performs addition, subtraction, multiplication, and division on fractions and mixed numbers, always presenting the result in simplified form alongside its mixed-number equivalent. It shows each step of the calculation process, making it a practical study tool for students learning fraction arithmetic. Enter any proper fractions, improper fractions, or mixed numbers.
Frequently Asked Questions
Sobre Esta Calculadora
Fraction arithmetic requires finding common denominators for addition and subtraction, cross-multiplication for division, and simplification using the greatest common factor for every operation. These steps are straightforward individually but easy to make mistakes on when done manually — especially with larger numerators and denominators.
This calculator handles all four operations on both simple fractions and mixed numbers. It finds the least common denominator automatically, performs the operation, simplifies the result using the GCF, and converts improper fractions to mixed numbers. Each step is displayed so you can follow the process and check your own work.
Fraction calculations appear in cooking and recipe scaling, construction measurements (feet and inches), probability (expressing likelihoods as ratios), and algebra (solving equations with fractional coefficients). For students, seeing the steps is often more valuable than just seeing the answer.

Exemplo Resolvido
Adding 2/3 and 5/8
Entradas:
- Fraction 1: 2/3
- Fraction 2: 5/8
- Operation: Addition
Passo a Passo:
- Find the least common denominator (LCD) of 3 and 8: LCD = 24
- Convert first fraction: 2/3 = 16/24
- Convert second fraction: 5/8 = 15/24
- Add numerators: 16/24 + 15/24 = 31/24
- Check if simplifiable: GCF(31, 24) = 1, already in lowest terms
- Convert to mixed number: 31/24 = 1 and 7/24
