Example Calculations

Adding Fractions
1/2 + 1/3 = 3/6 + 2/6 = 5/6 (0.8333...)
Subtracting Fractions
3/4 - 1/2 = 3/4 - 2/4 = 1/4 (0.25)
Multiplying Fractions
2/3 × 3/4 = 6/12 = 1/2 (0.5)
Dividing Fractions
1/2 ÷ 1/4 = 1/2 × 4/1 = 4/2 = 2/1 (2)

Frequently Asked Questions

How do I add fractions?

To add fractions, find a common denominator, convert both fractions, then add the numerators. Our calculator does this automatically and shows step-by-step solutions.

How do I simplify fractions?

Fractions are simplified by dividing both numerator and denominator by their Greatest Common Divisor (GCD). Our calculator automatically simplifies all results using the Euclidean algorithm.

How do I convert decimal to fraction?

Use the decimal converter section below the main calculator. Enter any decimal number and click Convert to see the equivalent fraction in simplified form.

Can I divide fractions?

Yes! To divide fractions, flip the second fraction (find its reciprocal) and multiply. Our calculator handles this automatically with the divide operation.

What if I enter zero as denominator?

The calculator will show an error message. Denominators cannot be zero as division by zero is undefined in mathematics.

How does the GCD algorithm work?

The calculator uses the Euclidean algorithm: gcd(a, b) = gcd(b, a % b). This efficiently finds the greatest common divisor to simplify fractions to their lowest terms.
