Find the lowest common denominator (LCD), convert each fraction, then add the numerators. Example: 1/2 + 1/3 → LCD=6 → 3/6 + 2/6 = 5/6.
Multiply numerators together and denominators together, then simplify. Example: 2/3 × 3/4 = (2×3)/(3×4) = 6/12 = 1/2.
Flip the second fraction (take its reciprocal) and multiply. Example: 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6.
Multiply the whole number by the denominator, then add the numerator. Example: 2 3/4 = (2×4 + 3)/4 = 11/4.
