How to Calculate Fractions
Fractions represent parts of a whole. To add or subtract fractions, you need a common denominator. To multiply, multiply numerators and denominators separately. To divide, multiply by the reciprocal of the second fraction.
Rules
- Addition: a/b + c/d = (ad + bc) / bd
- Subtraction: a/b - c/d = (ad - bc) / bd
- Multiplication: a/b × c/d = ac / bd
- Division: a/b ÷ c/d = ad / bc
