MATH / FRACTIONS
Fraction Calculator
Add, subtract, multiply, or divide two fractions and see the answer in lowest terms, mixed-number, decimal, and percent forms.
Set fraction inputs
Use the operation selector to choose the calculation.
Fraction result
Your fraction result will appear here
Enter two fractions and choose an operation, then calculate.
Exact arithmetic with useful conversions
Fractions are normalized, calculated, and reduced with integer numerator and denominator math. The result then appears as an improper fraction, mixed number when applicable, decimal, and percent.
Use exact input
Enter 3/4 instead of 0.75 when you want the fraction form preserved through the calculation.
Check division inputs
Division by a fraction with a zero numerator is rejected rather than returning an infinite or misleading result.
Frequently Asked Questions
Which fraction operations are supported?
The calculator supports addition, subtraction, multiplication, and division for two fraction inputs.
How should I enter a fraction?
Enter a fraction like 3/4, an integer like 2, or a decimal that can be represented as a finite fraction.
Will the result be simplified?
Yes. The result is reduced to lowest terms and also shown as a mixed number or decimal when useful.
What happens if I divide by zero?
The calculator reports an error when the right fraction is zero or has a zero numerator during division.
Does it show a step-by-step solution?
This version shows the normalized inputs and equivalent result forms. It does not render a full line-by-line derivation.
