What this fraction calculator does
The calculator adds, subtracts, multiplies, or divides two fractions or mixed numbers. It keeps the fraction calculation exact, reduces the answer with the greatest common divisor (GCD), and shows the main arithmetic steps. Decimal and percentage forms are secondary displays and are marked with an approximation sign when they must be rounded.
Use the working as a learning and checking aid. Your teacher, course, or exam may require a particular method or answer format, so compare the output with those instructions.
How to calculate fractions step by step
- Enter the first fraction: type its numerator on top and denominator below. For a mixed number like 2 1/3, put 2 in the Whole field.
- Choose the operation you need: add (+), subtract (−), multiply (×), or divide (÷).
- Enter the second fraction (and its whole number, if any) the same way, then press Calculate.
- Read the exact simplified result first. Decimal and percentage values may be rounded, and the approximation sign shows when that happens.
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 unsimplified fraction, exact simplified fraction, mixed number, decimal, and percentage.
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?
The tool shows the main arithmetic steps: mixed-number conversion when needed, the least common denominator for addition or subtraction, the operation, and GCD simplification.
Are fractions automatically simplified?
Yes. Each exact fraction result is reduced with the greatest common divisor. Decimal and percentage forms are marked as approximate when rounding is required.
Is the fraction calculator free and private?
Yes. It needs no sign-up. Inputs and session history stay in the current browser tab and are not automatically saved or uploaded.
