- A ratio table lists equivalent ratios. Each row multiplies both numbers by the same factor.
- Frame: "Each cup of mix needs ____ cups of water, so ____ cups of mix need ____ cups of water."
👀 See It
| Cups of mix | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| Cups of water | 3 | 6 | 9 | 12 |
The ratio stays 1 : 3 in every column. Each "water" is 3 times the "mix".
