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

This fraction calculator handles addition, subtraction, multiplication, and division of fractions and mixed numbers with step-by-step solutions. Enter any two fractions and the tool finds common denominators, performs the operation, and simplifies the result automatically. It shows each step of the working so students can learn the process, not just get the answer. The calculator also converts between fractions, decimals, and percentages.
