Okay, let's compare the two numbers:

9.11
9.9

When you compare decimal numbers, you compare them digit by digit starting from the left.

In this case, the first digit of 9.11 is 9 and the first digit of 9.9 is also 9. Since the first digits are the same, we move to the second digit.

The second digit of 9.11 is 1, while the second digit of 9.9 is 9.

Since 9 is greater than 1, the number 9.9 is larger than 9.11.

Therefore, 9.9 is larger than 9.11.
