No, you're not correct. 9.9 is greater than 9.11.

Think of it this way: 9.9 is the same as 9.90, and 9.90 is greater than 9.11 (since 90 hundredths is more than 11 hundredths).

This is a common point of confusion, sometimes because people mentally compare it to version numbers (where 9.11 would come after 9.9) or because "11" looks bigger than "9." But as decimal numbers, 9.9 > 9.11.
