Fraction Calculators
Use these fraction calculators to simplify, convert, and perform operations on fractions, mixed numbers, and ratios. Each calculator shows complete step-by-step working and provides results in multiple formats including simplified fractions, mixed numbers, decimals, and percentages.
Core Calculators
Reducing Fraction Calculator
Simplify any fraction to its lowest terms. Shows the greatest common divisor (GCD) method and explains how to identify when a fraction is already in simplest form.
Use this when you need to simplify fractions for homework, recipes, or measurements.
Number + Fraction Calculator
Convert whole numbers combined with fractions into improper fractions or mixed numbers. Handles addition of integers and fractional parts with automatic simplification.
Useful for converting recipe measurements or working with mixed quantities.
Ratio Simplifier
Simplify ratios to their lowest terms and convert between ratio notation (a:b) and fraction notation (a/b). Shows the common factor used for simplification.
Essential for scale drawings, mixing ratios, and proportion problems.
Mixed Numbers Calculator
Add, subtract, multiply, and divide mixed numbers. Automatically converts between mixed numbers and improper fractions as needed, then simplifies the final result.
Perfect for construction measurements, cooking, and everyday math with mixed quantities.
Mixed Numbers to Percent
Convert mixed numbers and fractions to percentage form. Shows the conversion process from mixed number to improper fraction to decimal to percent.
Helpful for calculating discounts, grades, and statistical representations.
Fractions Estimating Calculator
Compare and estimate fraction values quickly. Useful for mental math checks and understanding relative sizes of different fractions.
Great for quick checks when exact values aren't immediately needed.
How to Choose the Right Calculator
