Exemplars (from the NaCCA curriculum)

E.g. 1. To compare and order a mixture of common, decimal and percent fractions, express them in one form (i.e. either common, decimal or percent); e.g. to order 4/5, 0.78 and 85% (i) we can express all as decimals -> 4/5 = 80/100; 0.78 = 78/100 and 85% = 85/100, hence the order from least to the largest is 0.78, 4/5 and 85%; (ii) we can also express all as percentages -> 4/5 = 80/100 = 80%, 0.78 = 79/100 = 79%, and 85/100 = 85%, hence the order from least to the largest is 0.78, 4/5 and 85%.
E.g. 2. To compare and order a mixture of common, decimal and percent fractions you can locate the fractions on the number and order them.

 The fractions are stacked and are written inline. In E.g. 1 the page prints "0.78 = 79/100 = 79%" where 78/100 would be expected; it is transcribed as printed.
