Compare ratios by changing them to the form m : 1 or 1 to m.
For example:
• The ratios of shots taken to goals scored by two hockey teams are
17 : 4 and 13 : 3 respectively. By changing each ratio to the form m
: 1, say which is the more accurate team.
Interpret and use ratio in a range of contexts.
