Calculadora de Frações

Some, subtraia, multiplique e divida frações com passo a passo.

Introdução

Fraction Calculator — Add, subtract, multiply, and divide fractions with steps. Enter Numerator 1, Denominator 1, Operation, Numerator 2, Denominator 2 to get an instant, accurate result.

Fórmula

Add/subtract: a/b ± c/d = (ad ± cb)/bd. Multiply: (a/b)×(c/d) = ac/bd. Divide: (a/b)÷(c/d) = ad/bc. Result is simplified by dividing by the GCD.

Passo a passo

  1. Enter the Numerator 1.
  2. Enter the Denominator 1.
  3. Enter the Operation.
  4. Enter the Numerator 2.
  5. Enter the Denominator 2.
  6. Click Calculate to see your result instantly.

Exemplo do mundo real

Example: With Numerator 1 = 1, Denominator 1 = 2, Operation = +, Numerator 2 = 1, Denominator 2 = 3, the Fraction Calculator gives N: 5, D: 6, Decimal: 0.8333.

Perguntas Frequentes

Does it simplify the result automatically?
Yes, the numerator and denominator are always reduced by their greatest common divisor.
Can I use negative fractions?
Yes, enter a negative numerator or denominator and the sign carries through correctly.
What inputs does the Fraction Calculator need?
You'll need to provide: Numerator 1, Denominator 1, Operation, Numerator 2, Denominator 2. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Fraction Calculator?
The Fraction Calculator applies the formula exactly as calculated — Add/subtract: a/b ± c/d = (ad ± cb)/bd. Multiply: (a/b)×(c/d) = ac/bd. Divide: (a/b)÷(c/d) = ad/bc. Result is simplified by dividing by the GCD. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Fraction Calculator free to use?
Yes, the Fraction Calculator is completely free, requires no signup, and runs instantly in your browser.

Sobre a Calculadora de Frações

The Fraction Calculator uses a real, verifiable formula — Add/subtract: a/b ± c/d = (ad ± cb)/bd. Multiply: (a/b)×(c/d) = ac/bd. Divide: (a/b)÷(c/d) = ad/bc. Result is simplified by dividing by the GCD. — so results are accurate every time, not an approximation.
