To determine which row does not have the same ratio of galloons of lemonade to pounds of sugar, we can calculate the ratio for each row and compare them.
-
Row 1:
- Gallons of Lemonade: 2
- Pounds of Sugar: 40
- Ratio: \( \frac{2}{40} = \frac{1}{20} = 0.05 \)
-
Row 2:
- Gallons of Lemonade: 5
- Pounds of Sugar: 100
- Ratio: \( \frac{5}{100} = \frac{1}{20} = 0.05 \)
-
Row 3:
- Gallons of Lemonade: 6
- Pounds of Sugar: 135
- Ratio: \( \frac{6}{135} = \frac{2}{45} \approx 0.0444 \)
-
Row 4:
- Gallons of Lemonade: 12
- Pounds of Sugar: 240
- Ratio: \( \frac{12}{240} = \frac{1}{20} = 0.05 \)
Now, comparing the ratios:
- Rows 1, 2, and 4 all have the same ratio of \( \frac{1}{20} \) or 0.05.
- Row 3 has a different ratio of \( \frac{2}{45} \) or approximately 0.0444.
Therefore, the row that does not have the same ratio as the others is c. Row 3.
