9.11 is *less* than 9.9.

Think of them as decimals with the same number of digits:

- 9.11  
- 9.90  (this is the same value as 9.9)

Compare digit by digit:
- The 9 before the decimal: equal.
- First decimal place: 1 vs 9 → 1 < 9, so 9.11 < 9.90.

Another way:  
9.11 = 9 + 0.11  
9.9  = 9 + 0.9  

0.11 is less than 0.9, so 9.11 is less than 9.9.
