Manipulating algebraic fractions is a skill required in some of the trickiest algebra questions in the GCSE. For example, you have to use this skill (together with expanding and factorising) to make x the subject of the following:

\( \dfrac{x+1}{x+3} = t\)

Remember, that the principles are the same as for numerical fractions, so if you have a really good understanding of N2b – Applying the four operations to fractions, you should be in a good position. These lessons also follow on from this one:
