To find the average of these percentages, follow these steps:

1. Add all the percentages: $25.93 + 32.05 + 20.73 + 34.62 + 37.50 + 46.29 + 60 + 17.65 + 41.67 = 316.44$

2. Divide the sum by the number of values (which is 9 in this case): $\frac{316.44}{9} = 35.6\%$

So, the average of these percentages is 35.6%.
