Fraction Calculator
Use this fraction calculator for adding, subtracting, multiplying and dividing fractions. Answers are fractions in lowest terms or mixed numbers in reduced form.
Basic Fraction Calculator
Input proper or improper fractions, select the math sign and click Calculate. This fraction calculator includes steps shown in the answer.
Mixed Numbers Calculator
Calculate with mixed numbers (whole numbers with fractions). Enter numbers like '1 2/3' or '2 3/4'.
How to Use
- Enter your fractions using the numerator and denominator fields
- Select the operation you want to perform (+, -, ×, ÷)
- Click Calculate to see the result with step-by-step solution
Tip: keep denominators nonzero, and use multiplication when a word problem says one fraction is "of" another.
Tips & Notes
- For proper fractions, make sure the numerator is less than the denominator
- For mixed numbers, enter them in the format: 'whole number space fraction' (e.g., '1 2/3')
- When you see 'of' between fractions (like '1/2 of 3/4'), use multiplication
Example Calculations
- 1/2 + 1/4 = 3/4
- 3/4 - 1/2 = 1/4
- 2/3 × 3/4 = 1/2
- 1/2 ÷ 1/4 = 2
Features
- Basic fraction operations (add, subtract, multiply, divide)
- Mixed number support
- Automatic fraction simplification
- Convert between mixed numbers and improper fractions
Fraction Calculator FAQ
What can a fraction calculator do?
A fraction calculator can add, subtract, multiply, divide, and simplify fractions while showing the result in reduced form.
Why does the calculator simplify the answer?
Fractions are usually presented in lowest terms so the result is easier to read, compare, and use in later calculations.
What is the difference between proper, improper, and mixed fractions?
A proper fraction has a numerator smaller than its denominator, an improper fraction has a numerator greater than or equal to the denominator, and a mixed number combines a whole number with a fraction.
Why can't the denominator be zero?
Division by zero is undefined in mathematics, so a valid fraction must always have a nonzero denominator.
