Fraction Calculator — How to Add, Subtract, Multiply, and Divide Fractions
Adding and subtracting fractions requires a common denominator. Find the least common multiple (LCM) of the denominators, convert both fractions to equivalent fractions with that denominator, then add or subtract the numerators. For example, 1/2 + 1/3: LCM of 2 and 3 is 6, so 1/2 = 3/6 and 1/3 = 2/6, giving 5/6. Multiplying fractions is simpler: multiply the numerators together and the denominators together, then simplify. Dividing fractions means multiplying by the reciprocal of the divisor: 1/2 ÷ 1/3 = 1/2 × 3/1 = 3/2. Always simplify the result by dividing numerator and denominator by their greatest common divisor (GCD).
