Understanding multiplicative relationships: fractions and ratio

This unit introduces the concept of multiplicative relationsihps, and connects fractions to the idea of ratios. Ratios are then explored in depth and used to solve contextual problems such as those involving exchange rates and general conversions.

Source curriculum references

  • Use standard units of mass, length, time, money and other measures, including with decimal quantities
  • Appreciate the infinite nature of the sets of integers, real and rational numbers
  • Change freely between related standard units [for example time, length, area, volume/capacity, mass]
  • Use scale factors, scale diagrams and maps
  • Express 1 quantity as a fraction of another, where the fraction is less than 1 and greater than 1
