Fraction Calculator
Use a free online fraction calculator that displays stacked fractions and evaluates arithmetic, roots, powers, and scientific functions.
Fraction calculator with real stacked fraction input
This fraction calculator is built for expressions that are hard to read in a single text line.
Type / or use the fraction button to create a stacked numerator and denominator, then combine fractions with roots, powers, logs, and trigonometry.
Features
- Stacked fraction input with numerator and denominator fields.
- Addition, subtraction, multiplication, and division of fractions.
- Fraction expressions mixed with roots and powers.
- Decimal results with fraction approximations when useful.
- LaTeX copy for reusing fraction expressions in notes or documents.
Example expressions
\frac{1}{2}+\frac{1}{3}\frac{3}{4}\times\frac{8}{9}\frac{3}{4}\div\frac{2}{5}\frac{1+\sqrt{5}}{2}\sqrt{\frac{9}{16}}\frac{\log(100)}{\ln(e^2)}
How to use this calculator
- Press / or the a/b button to create a fraction.
- Fill the numerator and denominator, then use Tab or arrow keys to move through the expression.
- Press Enter to evaluate and check the decimal or fraction approximation.
Common input mistakes
- Do not type 1/2/3 unless you mean left-to-right division; use stacked fractions for clarity.
- Put long numerators or denominators inside the fraction structure before calculating.
- Use multiplication explicitly or rely on the calculator's implicit multiplication only when the expression is clear.
FAQ
How do I enter a fraction?
Press / on the keyboard or use the a/b button to create a fraction structure.
Can I calculate fractions with square roots?
Yes. You can put roots, powers, constants, and functions inside the numerator or denominator.
Can I copy the fraction as LaTeX?
Yes. Use the LaTeX copy button after entering the expression.
Does the calculator reduce fractions?
It calculates the decimal result and shows a fraction approximation when the value can be represented cleanly.
