Frequently Asked Questions
- Find a common denominator, convert each fraction, then add the numerators. Example: 1/2 + 1/3 = 3/6 + 2/6 = 5/6.
- Divide both numerator and denominator by their GCD. Example: 6/8 → GCD=2 → 3/4.
- Multiply numerators together and denominators together: (a/b) × (c/d) = ac/bd.
- Multiply the first fraction by the reciprocal of the second: (a/b) ÷ (c/d) = (a/b) × (d/c) = ad/bc.
- An improper fraction has a numerator larger than its denominator, e.g. 7/4. It equals the mixed number 1¾.
