Answer 1

To find the row that does not have the same ratio of gallons to cups, we can calculate the ratio for each row and see if they are the same.

1. **Row 1**: 2 gallons to 32 cups
\[
\text{Ratio} = \frac{32 \text{ cups}}{2 \text{ gallons}} = \frac{32}{2} = 16
\]

2. **Row 2**: 5 gallons to 80 cups
\[
\text{Ratio} = \frac{80 \text{ cups}}{5 \text{ gallons}} = \frac{80}{5} = 16
\]

3. **Row 3**: 9 gallons to 134 cups
\[
\text{Ratio} = \frac{134 \text{ cups}}{9 \text{ gallons}} \approx 14.89
\]

4. **Row 4**: 12 gallons to 192 cups
\[
\text{Ratio} = \frac{192 \text{ cups}}{12 \text{ gallons}} = \frac{192}{12} = 16
\]

The ratios are:
- Row 1: 16
- Row 2: 16
- Row 3: 14.89 (not 16)
- Row 4: 16

From this, we can see that **Row 3 does not have the same ratio** as the other rows. Thus, the answer is:

**Row 3**.
