How It Works
Addition / Subtraction
a/b ± c/d = (ad ± bc) / bd
Multiplication
a/b × c/d = ac / bd
Division
a/b ÷ c/d = ad / bc
Tips
• Leave whole number empty or 0 for simple fractions
• Use negative numbers for subtraction
• Results are automatically simplified using GCD
• Denominators cannot be zero
Frequently Asked Questions
What operations does the fraction calculator support?
The calculator supports addition, subtraction, multiplication, and division of fractions and mixed numbers. Each result shows the answer as a fraction, simplified fraction, mixed number, and decimal.
Can I use mixed numbers like 2 1/3?
Yes. Enter the whole number in the "Whole" field and the fraction part in the numerator and denominator fields. For example, for 2 1/3, enter 2 as the whole, 1 as numerator, and 3 as denominator.
How does the step-by-step solution work?
After each calculation, the tool shows every step: converting mixed numbers to improper fractions, finding the LCD for addition/subtraction, performing the operation, and simplifying the result using the GCD.
Are fractions automatically simplified?
Yes. Every result is automatically reduced to its simplest form using the GCD algorithm. The unsimplified result is also shown so you can see both forms.
Is the fraction calculator free?
Yes, completely free with no sign-up required. All features including step-by-step solutions, mixed number support, and calculation history are available at no cost.
