Algebraic fractions can be simplified by cancelling down. To do this the NUMERATORS and DENOMINATORS must be fully factorised first.

Key Points Algebraic Fractions
If the Numerator and Denominator contain fractions then you can multiply both by the same number (LOWEST COMMON MULTIPLE) to create an equivalent fraction.

Key Points Algebraic Fractions
To multiply fractions, you simply multiply the numerators and multiply the denominators.(IF POSSIBLE CANCEL DOWN FIRST).

Key Points Algebraic Fractions
To divide two fractions, MULTIPLY the first fraction by the RECIPROCAL of the second fraction.

Key Points Algebraic Fractions
To add (or subract) fractions each fraction MUST have the SAME denominator. This is done by finding the LOWEST common multiple of the denominators.

Key Points Algebraic Fractions
When the numerator has the same or higher degree than the denominator, you can divide the terms to produce a 'MIXED' number fraction. This can be done either by using long division or by using the remainder theorem: F(x)= Q(x) X divisor + remainder
