Free Fraction Calculators
15 fraction tools. Fast, accurate, and completely free.
Quick Answer
Add fractions: find LCD, convert, add numerators. Multiply: just multiply across: 2/3 × 3/5 = 6/15 = 2/5
Example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12

About FracCalc
FracCalc provides 15 free online fraction calculator tools covering basic operations, conversions, and comparisons. All calculations run in your browser for instant results — no server needed, no registration required. Every tool shows the formula and step-by-step working so you can understand the math, not just get the answer.
Basic Fraction Operations
The basic fraction tools cover the four arithmetic operations (addition, subtraction, multiplication, division) along with simplification and equivalent fraction finding. The Fraction Calculator handles all four operations on proper fractions and improper fractions, showing the intermediate steps including finding the least common denominator for addition and subtraction. The Mixed Number Calculator extends this to mixed numbers like 2 3/4. The Simplify Fraction tool uses the Euclidean GCD algorithm to reduce any fraction to its lowest terms instantly, even for large numerators and denominators.
Fraction Conversions
Fractions, decimals, percentages, and ratios are four ways to express the same numerical value. The convert tools handle all five common conversions: fraction to decimal (divide numerator by denominator), decimal to fraction (write over appropriate power of 10 and simplify), fraction to percentage (multiply decimal by 100), percentage to fraction (write over 100 and simplify), and ratio to fraction. The tools handle both terminating decimals (like 0.75 = 3/4) and repeating decimals (like 0.333... = 1/3).
Fraction Comparisons
The compare tools answer questions like "which fraction is larger?", "how do I sort these fractions?", and "what is the common denominator for these fractions?". The Compare Fractions tool uses cross-multiplication to determine which of two fractions is greater. The Order Fractions tool sorts up to six fractions from smallest to largest by converting to a common denominator. The Fraction Number Line visualizes fractions on a number line, making it easy to see their relative positions and understand magnitude intuitively.

Frequently Asked Questions
What is a fraction?
A fraction represents a part of a whole, written as a/b where 'a' is the numerator (parts taken) and 'b' is the denominator (total equal parts). For example, 3/4 means 3 out of 4 equal parts.
How do I add fractions with different denominators?
Find the least common denominator (LCD), convert both fractions to equivalent fractions with that denominator, then add the numerators. Example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12. Use our fraction calculator for instant results.
How do I convert a fraction to a decimal?
Divide the numerator by the denominator. For example, 3/4 = 3 / 4 = 0.75. Some fractions produce repeating decimals, like 1/3 = 0.333... Try our fraction to decimal converter.
How do I simplify a fraction?
Find the greatest common divisor (GCD) of the numerator and denominator, then divide both by it. For example, 12/18: GCD(12,18) = 6, so 12/18 = 2/3. Use our simplify fraction tool.
