To find the unit rate of chairs per table, divide the total number of chairs by the number of tables.
You have 12 chairs and 2 tables:
\[ \text{Chairs per table} = \frac{\text{Total chairs}}{\text{Number of tables}} = \frac{12 \text{ chairs}}{2 \text{ tables}} = 6 \text{ chairs per table} \]
So, the unit rate is \(6\) chairs per table.
