              Direct Proportion and Exchange Rates

              Students learn how to use ratio notation to convert between exchange rates.

              Learning progresses from working with proportions in the form 1 : n to finding conversion factors from a real-life graph.

              Differentiated Learning Objectives
              • All students should be able to calculate proportionate amounts in the form 1 : n.
              • Most students should be able to calculate proportionate amounts using equivalent ratios.
              • Some students should be able to solve problems involving equivalent ratios in context.
