Ratio and Proportion
Subjects / Maths / Number
In this title, we'll cover what ratios are used for, how to write them and how to simplify them. We'll explain how to share in a given ratio, as well as considering the unitary method of direct proportion. For those sitting the Higher level paper, we'll look at what inverse proportion means, how we can work out the constant of proportionality and we'll consider writing formulae that connects different variables. To help us explain all this, we'll be looking at wine gums, charities, boys, recipes, girls, toilet roll and starting up your own business, so there should be something for everyone! Don't forget to 'Test Yourself' using the questions after Chapter Four.
