To find the row that does not have the same ratio of gallons of lemonade to teaspoons of sugar, we can calculate the ratio for each row.
-
Row 1:
- 2 gallons of lemonade contributes 40 teaspoons of sugar.
- Ratio = 40 tsp / 2 gal = 20 tsp/gal.
-
Row 2:
- 5 gallons of lemonade contributes 100 teaspoons of sugar.
- Ratio = 100 tsp / 5 gal = 20 tsp/gal.
-
Row 3:
- 6 gallons of lemonade contributes 135 teaspoons of sugar.
- Ratio = 135 tsp / 6 gal = 22.5 tsp/gal.
-
Row 4:
- 12 gallons of lemonade contributes 240 teaspoons of sugar.
- Ratio = 240 tsp / 12 gal = 20 tsp/gal.
After calculating the ratios:
- Row 1, Row 2, and Row 4 all have a ratio of 20 tsp/gal.
- Row 3 has a different ratio of 22.5 tsp/gal.
Thus, the row that does not have the same ratio as the others is Row 3.
