Actually, 9.9 is greater than 9.11.

When comparing decimal numbers, we compare digit by digit from left to right:
- Both numbers have 9 in the ones place
- In the tenths place: 9.9 has 9, while 9.11 has 1
- Since 9 > 1 in the tenths place, 9.9 is greater

Another way to think about it: 9.9 = 9.90, and 90 hundredths is greater than 11 hundredths.
