Which of these values are closest to the percentage difference in the usage of gas per hour, of the smaller burner over the larger burner?

Step 1: Ratio approach. Rate_small/Rate_large = 80/104 = 10/13.
Step 2: Percentage. (1-10/13)x100 = 3/13 x100 = 23.077%
Final Answer: 23.07%.
Step 2: Percentage. (1-10/13)x100 = 3/13 x100 = 23.077%
