Part 5:

Ratio and Proportion |
| Ratio Ratio is a way of comparing two or more quantities. For instance, if a garage sold red cars and blue cars in the ratio 4 : 3 (read 'four to three') then it means that for every 4 red cars sold there were 3 blue cars sold. In each case, the proportion of red cars to blue cars remains the same, 4 : 3. |
