Does it handle mixed numbers?

Yes, you can input mixed numbers, and the calculator will convert them as needed to find the result.

Is it safe to use Edita for sensitive files?

Absolutely. Edita processes all your files locally in your browser using WASM (WebAssembly) technology. Your documents never leave your device and are never uploaded to our servers, ensuring total privacy.

Does Edita store my data or file history?

No. We have a strict 'no-storage' policy. Once you close your browser tab, all traces of your processed files are gone. We don't track your content or keep any logs of your file data.

Why is Edita faster than other online converters?

Traditional tools require you to upload large files to a server, wait for processing, and then download them back. Edita eliminates all network lag by processing everything instantly on your own hardware.

What Is a Fraction Calculator?

A fraction calculator performs arithmetic (addition, subtraction, multiplication, division) on fractions — proper fractions, improper fractions, and mixed numbers — and returns the result in its simplest reduced form. It handles the LCM-finding, cross-multiplication, and GCD-reduction steps automatically.

Operations Explained

Addition/Subtraction: Find LCD, convert both fractions, add/subtract numerators, reduce.
Multiplication: Multiply numerators, multiply denominators, reduce.
Division: Multiply by the reciprocal of the divisor (flip-and-multiply), then reduce.
Simplification: Divide numerator and denominator by their GCD to reach lowest terms.

Who Uses It

Students in Class 5–10 studying fractions and rational numbers. Adults calculating recipe scaling (½ cup × ⅔ = ?), material measurements in construction (⅜ inch + 11/16 inch), or medication dosing. Teachers verifying student answers.
