Actually, in numeric comparison, 9.11 is not greater than 9.9. The confusion might arise from the decimal points and the placement of numbers. Decimal values are compared digit by digit from left to right after the decimal point. 

So, here's how you compare 9.11 and 9.9:
- The integer part, 9, is the same for both numbers.
- After the decimal point, you compare the first digit: 1 (in 9.11) versus 9 (in 9.9). Since 9 is greater than 1, 9.9 is greater than 9.11.

Therefore, 9.9 is actually greater than 9.11.
