Fraction Calculator
Perform all four core arithmetic operations (addition, subtraction, multiplication, and division) on fractions, improper fractions, and mixed numbers.
Basic Fraction Calculator
Add, subtract, multiply, or divide two fractions.
Calculation Examples
How to Use the Fraction Calculator?
Enter fractions (example: 1/2 + 3/4) or choose the operation and enter the numbers. When you're ready, click "Calculate," and you will get your answer, along with the simplified form and decimal. This tool adds, subtracts, multiplies, and divides them, while also using the least common denominator (LCD) when adding or subtracting fractions, and cross-multiply to divide or multiply fractions.
Understanding Fractions in Mathematics
A fraction represents a part of a whole, expressed as a numerator above a denominator. For example, in the fraction $\frac{3}{8}$, the number $3$ is the numerator and $8$ is the denominator. This signifies 3 out of 8 equal parts. Note that the denominator cannot be zero, as division by zero is undefined.
Useful Tips 💡
- Always reduce fractions to their lowest terms for the clearest result.
- For division, remember the rule: "Keep the first, Change the sign, Flip the second."
📋Steps to Calculate

Enter fractions or decimals.
-
Choose operation (add, subtract, multiply, divide).
-
Click "Calculate" to see simplified results.
Mistakes to Avoid ⚠️
- Failing to find a Least Common Denominator (LCD) before adding or subtracting fractions.
- Dividing fractions by forgetting to invert (flip) the second fraction and multiplying (Keep-Change-Flip method).
- Improperly converting mixed numbers to improper fractions (e.g., multiplying the whole number only by the denominator).
- Thinking 1/2 + 1/2 = 2/4 instead of simplifying the final answer to 1.
