A series of 12 programmes 6: Ratio
The great advantage of ratios is that no units are involved; the ratios of the constituents of a cocktail are the same whether a glassful or a bucketful is to be made. By turning the ratios into fractions and building them into a table, this programme develops a systematic way of handling ratios - no matter how many constituents are involved.
