In this unit, students will learn how to use ratio and proportion in Maths. They will start by learning how to write ratios, including using unitary form and simplest form, before splitting quantities in ratios and using ratios to find unknown amounts. Students will then look at the links between ratio and fractions, and how ratio can be used to write linear functions and scale up quantities in direct proportion. They will then apply this to the specific cases of scaling up recipes, maps, scale models and currency conversions.
