use mathematical modelling to solve practical problems involving ratios; formulate problems, interpret and communicate solutions in terms of the situation, justifying choices made about the representation

Elaborations

• 1 using fractions to model and solve ratio problems involving comparison of quantities, and considering part-part and part-whole relations
• 2 modelling and solving practical problems involving ratios of length, capacity or mass, such as in construction, design, food or textile production; for example, mixing concrete, the golden ratio in design, mixing a salad dressing
• 3 modelling the situation using manipulatives, diagrams and/or mathematical discussion; for example, mixing primary colours in a variety of ratios to investigate how new colours are created and the strength of those colours
• 4 investigating commercialised substances founded on First Nations Australians’ knowledges of substances including pharmaceuticals and toxins, understanding how ratios are used in their development
