Calculations – for example:
- creating a budget for living at home and for living independently
- using timesheets, which include overtime, to calculate weekly wages
- converting between weekly, fortnightly and yearly incomes.
Percentages – for example:
- expressing ingredients of packaged food as percentages of the total quantity, or per serving size, or per 100 grams
- comparing the quantities, both numerically and in percentage terms, of additives within a product or between similar products, such as flavours
- calculating commissions, including retainers from sales information.
Rates – for example:
- using rates to compare and evaluate nutritional information, such as quantity per serve and quantity per 100g
- calculating heart rates as beats per minute, given the number of beats and different time periods
- applying rates to calculate the energy used in various activities over different time periods
- completing calculations with rates, including solving problems involving direct proportion in terms of rate; for example, if a person works for 3 weeks at a rate of $300 per week, how much do they earn?
- analysing and interpreting tables and graphs that compare body ratios such as hip height versus stride length, foot length versus height.
