Number > Fractions, Decimals and Percentages

Australian Curriculum Version 9 Says:

Solve problems that require finding a familiar fraction, decimal or percentage of a quantity, including percentage discounts, choosing efficient calculation strategies and using digital tools where appropriate.

What this means

Calculating a fraction or a percentage of a number or multiplying a number by a decimal.

Examples include:

  • 1/4 × 24 – solving through division 24 ÷ 4
  • 25% of 50 might be solved by multiplying 50 by 0.25
  • Students would need to be familiar with fraction, decimal percentage equivalents e.g., ¼ = 0.25 = 25%

Tip

Note: links may be made to Fact Families for multiplication and division. That is;

  • 3 × 4 = 12
  • 12 ÷ 3 = 4
  • 1/3 of 12 = 4
  • 4 × 3 = 12
  • 12 ÷ 4 = 3
  • 1/4 of 12 = 3
