Ratio & Proportion (Pre-GCSE)

(Used for Tiffin Year 9 scheme of work) (a) Methods for solving problems involving direct and indirect proportion, including the unitary method (but not quadratic/cubic/root relationships). (b) Problems involving ratio. (c) Extension: 3 way relationships, e.g. "If it takes a men b hours to dig c holes..." This (intentionally) does not make reference to the GCSE method of establishing the constant of proportionality.
