No, \( 9.11 \neq 9.9 \).

To compare the numbers 9.11 and 9.9:

- 9.11 has a tenths digit of 1 and a hundredths digit of 1.
- 9.9 has a tenths digit of 9 and no hundredths digit (or you could think of it as having a hundredths digit of 0).

Since 9.1 (the first two digits of 9.11) is less than 9.9, 9.11 is not equal to 9.9. Furthermore, 9.11 is actually less than 9.9. 

### Detailed comparison:
- \(9.11 = 9 + 0.11\)
- \(9.9 = 9 + 0.9\)

Since \(0.11 < 0.9\), it follows that \(9.11 < 9.9\).
