Answer: %836
Solve the proportion by multiplying the two numbers in opposite corners and dividing by the number in the corner opposite the '?' 
Examples: 

8 9/25 change the mixed number to a improper fraction by multipling the 25 by 8=200 then add 200+9 giving you 209/25 as the improper fraction. 

Then you'll need to convert 209/25 = ?/100 divide 25 into 100 =4. then multiply 209*4= 836 so the answer is 836%
