What is an algebraic fraction?

• An algebraic fraction is simply a fraction with an algebraic expression on the top (numerator) and/or the bottom (denominator)

Adding & subtracting

• Rules same as numeric fractions:

1. Find the lowest common bottom (denominator)
2. Write fractions with new bottoms
3. Multiply tops by the same as bottoms
4. Write as a single fraction (take care if subtracting)
5. Simplify the top

• Always leave your answer in as simple a form as possible (see Algebraic Fractions – Simplifying)
