Ratio - harder GCSE style questions

GCSE maths questions on ratio are becoming increasingly more difficult and these two worksheets aim to give a flavour of what is now required, with several variables as different expressions. One sheet requires you to show that a particular ratio is achieved (so pupils can see if they have the method correct). The second sheet is the same set of questions but in the style of finding a particular ratio (so pupils won’t automatically know whether they have got it correct, so a bit more challenging).
Textbook questions seem to be a bit thin on the ground so I wrote these as an extra resource for my pupils.
