Free Online Fraction Calculator with Mixed Numbers & Decimals

Working with math fractions—whether adding, subtracting, multiplying, or dividing—can quickly become confusing when finding common denominators or reducing improper fractions to lowest terms. Whether you are a student solving math homework, an engineer checking blueprint measurements, or a chef adjusting recipe proportions, an accurate fraction calculator simplifies your math.

Tooloraa's online fraction calculator lets you calculate fraction equations online free with instant accuracy. Enter your numerators and denominators, select your desired operation, and get simplified fractions, mixed numbers, and decimal conversions in seconds.

How Fraction Arithmetic Works

Depending on the selected operator, our tool applies standard algebraic rules to calculate exact fraction outputs:

Addition: (a/b) + (c/d) = (ad + bc) / bd
Subtraction: (a/b) - (c/d) = (ad - bc) / bd
Multiplication: (a/b) × (c/d) = ac / bd
Division: (a/b) ÷ (c/d) = ad / bc

Why Private Browser-Side Calculation is Safer

Most online calculators send your equations to remote cloud servers to process calculations, creating unnecessary privacy risks when working with proprietary business or research data.

Tooloraa operates on a 100% privacy-first model using client-side JavaScript. Your calculations run locally in your browser's RAM memory thread. They never leave your computer, ensuring complete confidentiality.

Tips & Best Practices for Fraction Calculations

  • Check Denominators: Ensure denominators are not set to zero to prevent division by zero errors.
  • Understand Improper Fractions: When the numerator is larger than the denominator, refer to the Mixed Number box for easier reading.
  • Use Decimal Conversion: Use the Decimal Float Value for quick conversions when working with measurements or financial items.

Frequently Asked Questions

Clear answers regarding fraction simplification, mixed numbers, and browser privacy protection.

Our calculator uses the Euclidean algorithm to find the Greatest Common Divisor (GCD) between the resulting numerator and denominator. It divides both numbers by the GCD to simplify the fraction to its lowest terms without rounding errors.
No, 100% private. All calculations happen locally inside your web browser thread. Your numbers, fraction inputs, and calculated results are never uploaded to remote servers, saved in databases, or tracked.
Yes. If the resulting numerator is larger than the denominator, the calculator automatically computes the whole number integer and remaining fraction remainder, displaying the result as a mixed number.
Yes. Tooloraa is built with a responsive touch-friendly layout. You can easily enter numerators and denominators, select math operators, and view results on any smartphone, tablet, or desktop browser.
Error messages appear if any denominator input is left blank or set to zero, or if you attempt to divide by a secondary fraction with a numerator of zero, which results in an undefined mathematical operation.
Yes. Our fraction calculator supports negative whole numbers. It automatically formats negative signs cleanly in the final simplified output.
A simplified fraction (or fraction in lowest terms) is a fraction whose numerator and denominator share no common factors other than 1. For example, 4/8 simplifies to 1/2.
To divide two fractions, you multiply the first fraction by the reciprocal (flipped version) of the second fraction. For example, (1/2) ÷ (3/4) = (1/2) × (4/3) = 4/6 = 2/3.
Yes. In addition to simplified proper and mixed fractions, the calculator displays the exact decimal value of the result up to 6 decimal places.
Your data is not stored anywhere. All inputs and calculated results exist only in your browser's temporary active memory and disappear permanently when you close or refresh the page.
