What is this tool?
Does exact fraction arithmetic — addition, subtraction, multiplication, and division of two fractions (or whole numbers), always reducing the answer to lowest terms using the greatest common divisor. Results also show as a mixed number (7/4 → 1 3/4) and a decimal. A separate simplify mode reduces any single fraction like 24/36 to 2/3.
How to use it
- Enter two fractions like 3/4 and 2/3 (whole numbers work too).
- Pick the operation: add, subtract, multiply, or divide.
- Read the simplified result, mixed-number form, and decimal — or switch to simplify mode.
