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.
