What is Fraction Calculator?
Fraction Calculator is an educational and professional math utility designed to add, subtract, multiply, and divide fractions. Fractions can be notoriously difficult to compute manually, especially when they have unlike denominators or involve mixed numbers. Our calculator takes two fractions (or mixed numbers) and provides the simplified fraction, mixed number, and decimal representation instantly, serving as a powerful assistant for woodworkers, cooks, students, and engineers.
How it works
The calculator computes fractional operations by finding the Least Common Denominator (LCD) for addition/subtraction, and performing direct numerator/denominator products for multiplication/division. It then applies the Greatest Common Divisor (GCD) algorithm to simplify the output to its lowest terms. All math is performed instantly on the client side.
Features & Benefits
- Handles addition, subtraction, multiplication, and division of fractions
- Results are automatically simplified to lowest terms
- Shows both the fraction form and decimal equivalent
- Runs entirely in your browser - no server needed
Frequently Asked Questions
How does fraction simplification work?
The result is divided by the greatest common factor (GCF) of the numerator and denominator to reduce it to lowest terms.
Can I enter negative fractions?
Yes. Use a negative numerator or denominator. The calculator normalises the sign to the numerator.
What if the denominator is zero?
Division by zero is undefined. The calculator will show 'undefined' for any fraction with a zero denominator.
