To compare 9.11 and 9.9, we can compare them digit by digit from left to right, starting with the whole number part.

Both numbers have the same whole number part, which is 9.

Now we move to the digit in the tenths place. In 9.11, the digit in the tenths place is 1. In 9.9, the digit in the tenths place is 9.

Since 1 is less than 9, the number with 1 in the tenths place is smaller than the number with 9 in the tenths place.

Therefore, 9.11 is less than 9.9.

Alternatively, we can add trailing zeros to 9.9 so that both numbers have the same number of decimal places. 9.11 has two decimal places. 9.9 can be written as 9.90 to have two decimal places.

Now we compare 9.11 and 9.90. We can compare the numbers after the decimal point: 11 and 90. Since 11 is less than 90, 9.11 is less than 9.90.

Thus, 9.11 is less than 9.9.

The question asks if 9.11 is greater than 9.9. Since 9.11 is less than 9.9, the answer is no.

The final answer is $\boxed{No}$.

No, 9.11 is not greater than 9.9.

Here's how to compare them:

Look at the whole number part: Both numbers have 9 before the decimal point, so they are equal so far.
Look at the tenths place (the first digit after the decimal):
- 9.11 has a 1 in the tenths place.
- 9.9 has a 9 in the tenths place.
Compare those digits: Since 1 is less than 9, the number 9.11 is less than 9.9.

Therefore, 9.9 is greater than 9.11.
