Result
📐 Adding Fractions
Find LCD, convert fractions, add numerators. Example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12
✖️ Multiplying
Multiply straight across: numerator × numerator, denominator × denominator. Then simplify.
➗ Dividing
Flip the second fraction and multiply. Example: 2/3 ÷ 3/4 = 2/3 × 4/3 = 8/9
🎯 Simplifying
Divide numerator and denominator by their GCD. Example: 6/8 → GCD=2 → 3/4
Frequently Asked Questions
How do you add fractions with different denominators?
Find the least common denominator (LCD) of both fractions, convert each to equivalent fractions with that LCD, then add the numerators and keep the denominator. For example: 1/3 + 1/4 → LCD is 12 → 4/12 + 3/12 = 7/12.
How do you multiply fractions?
Multiply the numerators together and the denominators together, then simplify. For example: 2/3 × 3/4 = (2×3)/(3×4) = 6/12 = 1/2. You can cross-cancel common factors before multiplying for easier math.
How do you simplify a fraction?
Find the greatest common divisor (GCD) of the numerator and denominator, then divide both by it. For example: 8/12 → GCD of 8 and 12 is 4 → 8÷4 / 12÷4 = 2/3. A fraction is fully simplified when the GCD is 1.
