The number **9.9** is greater than **9.11**. Here's why:

When comparing decimal numbers, we look at the digits from left to right:
1. The whole number part for both is **9**, so they are equal.
2. Moving to the first decimal place, we have **9** for 9.9 and **1** for 9.11. Since **9** is greater than **1**, it indicates that **9.9** is the larger number.

Thus:
\[
9.9 > 9.11
\]
