Each row of an equivalent ratio table uses one shared factor.
Optional until a teacher marks it
| 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.
Problem 1 of 8. What we learned, an example, a few together, then independent practice.
| blue tiles | yellow tiles |
|---|---|
| 3 | 5 |
| 6 | ? |
A ratio table shows 3 blue tiles for every 5 yellow tiles. How many yellow tiles go with 6 blue tiles?
Support frame: Factor = 6 ÷ 3. Second part = 5 × factor.
