Add Fractions Calculator
Enter two fractions to find their sum, simplified to lowest terms.
The Add Fractions Calculator helps you instantly add two fractions together and simplify the result, whether you're working with simple fractions like 1/2 or mixed fractions like 2 3/4. No more finding common denominators by hand — just enter your fractions and get the exact answer.
🔢 What Does It Mean to Add Fractions?
Adding fractions means combining two fractional quantities into a single fraction. Unlike adding whole numbers, fractions must share a common denominator before their numerators can be added — this calculator finds that common denominator, adds the fractions, and simplifies the result automatically.
📐 Fraction Addition Formula
The result is then simplified by dividing both the numerator and denominator by their greatest common divisor (GCD). For mixed fractions, each mixed number is first converted to an improper fraction using whole × denominator + numerator, then the same formula applies.
✍️ Example Calculation:
Suppose you want to add 1/4 and 1/6 (simple fractions).
For mixed fractions, suppose you add 1 1/2 and 2 1/3.
3/2 + 7/3 = (3×3 + 7×2) ÷ (2×3) = 23/6 = 3 5/6
