Find the Least Common Denominator (LCD), convert both fractions to equivalent fractions with the LCD, then add or subtract the numerators. Example: 1/2 + 1/3 = 3/6 + 2/6 = 5/6.
Multiply numerator × numerator and denominator × denominator. Then simplify. Example: 2/3 × 3/4 = 6/12 = 1/2.
Multiply the first fraction by the reciprocal of the second. Example: 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6.
Divide both numerator and denominator by their Greatest Common Factor (GCF). Example: 8/12 → GCF(8,12)=4 → 2/3.
