Tables of equivalent ratios are called ratio tables. Consider the ratio table containing the distance a person runs and the time it takes him to cover that distance.
| Distance Run (Miles) | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| Time (Minutes) | 10 | 20 | 30 | 40 |
The ratios 110, 220, 330, and 440 are equivalent since each of them simplifies to a ratio of 110. A ratio table can be created by multiplying or dividing each quantity in a ratio by the same number, or by repeatedly adding or subtracting the ratio.
