The number 9.9 is larger than 9.11.

When comparing decimals, we start by comparing the digits from left to right. In this case:

- 9.9 has one digit after the decimal (which is 9), while
- 9.11 has two digits after the decimal (which are 1 and 1).

Since 9.9 is the same as 9.90 (adding a zero doesn't change its value), you can now compare 9.90 and 9.11. Clearly, 9.90 is larger than 9.11.
