About Fraction Calculator

Use this fraction calculator to add, subtract, multiply, or divide fractions, mixed numbers, and whole numbers. It returns an exact reduced fraction, mixed number, decimal check, and concise steps locally in your browser.

Tool details and FAQUse cases, limits, privacy, and related tools

Overview

Enter two values with separate whole-number, numerator, and denominator fields, then choose an operation. The calculator handles proper fractions, improper fractions, mixed numbers, whole numbers, and negative values without requiring expression syntax. Results are reduced exactly and shown with a short operation-specific derivation.

Best for

  • Adding, subtracting, multiplying, or dividing two fractions exactly.
  • Entering mixed numbers and whole numbers without converting them by hand.
  • Checking a reduced improper fraction, mixed number, decimal value, and the calculation steps together.

Not for

  • Free-form expressions, chained calculations with more than two operands, or saved calculation history.
  • Algebra, equations, variables, graphing, continued fractions, or automatic homework-answer generation.
  • Certified, audited, or regulated calculations that require an approved system or retained record.

How it works

  1. Choose Add, Subtract, Multiply, or Divide.
  2. Enter the whole-number, numerator, and positive nonzero denominator parts for both values.
  3. Select Calculate to run one exact operation.
  4. Review the reduced improper fraction, mixed number, decimal check, and calculation steps.

Limits and privacy

This calculator performs one add, subtract, multiply, or divide operation between two structured values. Denominators must be positive and nonzero, and division by a zero-valued fraction is invalid. The reduced fraction is the exact result; the decimal check may be rounded for display. It does not parse arbitrary expressions, solve algebra, accept more than two operands, or save answer history. Inputs, exact results, and steps stay in the browser and are excluded from analytics and masked in session replay.

Common uses

  • Add unlike fractions and see how the denominators are aligned.
  • Subtract mixed measurements for woodworking, construction, or electrical work.
  • Multiply or divide recipe quantities and other everyday proportions.
  • Combine a whole number with a proper or improper fraction.
  • Check a homework or worksheet result in reduced, mixed-number, and decimal forms while reviewing the arithmetic steps.

Useful facts

  • Tiny Work Tools Fraction Calculator performs exact integer-based fraction arithmetic locally in the browser.
  • Every valid result is normalized to a positive denominator and reduced to lowest terms.
  • Negative inputs and results keep one normalized sign instead of requiring a negative denominator.
  • The decimal value is a convenient check; the reduced fraction remains the authoritative exact result.

FAQ

What can I enter in the fraction calculator?

You can enter proper fractions, improper fractions, mixed numbers, whole numbers, and negative values. Each operand uses separate whole-number, numerator, and denominator fields, so no expression syntax is required.

Can this calculator add and subtract mixed numbers?

Yes. Enter the whole-number and fraction parts for each value, choose Add or Subtract, and calculate. The result includes a reduced improper fraction, a mixed number when applicable, a decimal check, and denominator-alignment steps.

Does the fraction calculator simplify answers?

Yes. It reduces every valid fraction to lowest terms and normalizes the sign so the denominator is positive. An improper result is also shown as a mixed number when it has a nonzero whole part.

How are fractions with different denominators added or subtracted?

The calculator finds a common denominator, rewrites both fractions as equivalent fractions, combines the numerators, and reduces the result. The displayed steps show that sequence for the values you entered.

Can I divide by a fraction or by a whole number?

Yes. Division multiplies the first value by the reciprocal of the second. The second value cannot equal zero, including entries such as 0/5 or a whole number of 0.

Are my fraction inputs or answers uploaded or saved?

No. The calculation runs locally in your browser and does not save answer history. Operands, exact answers, decimal checks, and calculation steps are not included in analytics or readable session-replay content.
