If, for example, a boy has won fifteen games, and the ratio of his wins to losses is 3:2, a tape diagram can be used to determine his number of losses, such as by doing
| 15 | ? | ||
| Total games lost = ? | |||
|---|---|---|---|
| 3 | 2 | ||
| Total games lost = ? | |||
|---|---|---|---|
Since the ratio between his wins and losses is 3:2, and he has won fifteen games, it can be concluded that the boy has lost ten of these games.
