Standard practice
Each row of an equivalent ratio table uses one shared factor.
| blue tiles | yellow tiles |
|---|---|
| 3 | 5 |
| 6 | ? |
Amina uses 3 blue tiles for every 5 yellow tiles at the mural wall. The same relationship has to hold for a larger amount.
Each row of an equivalent ratio table is the base ratio multiplied by a whole-number factor. The columns stay matched because the factor is shared. Moving down a column by adding a fixed amount breaks that match.
