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:
- Find the lowest common bottom (denominator).
- Write fractions with new bottoms.
- Multiply tops by same thing as bottoms.
- Write as a single fraction (take care if subtracting)
- Simplify the top
Always leave your answer in as simple a form as possible
(See “Algebraic Fractions – Simplifying” for more on that)
