Math Misconception Test

No, 9.11 is not greater than 9.9.

To compare these numbers, I can look at them digit by digit:

• Both numbers have 9 in the ones place
• In the tenths place: 9.11 has 1, while 9.9 has 9
• Since 1 < 9, we can conclude that 9.11 < 9.9

Another way to see this is to write 9.9 as 9.90:

• 9.11 vs 9.90
• Clearly 9.11 < 9.90

Therefore, 9.9 is greater than 9.11.
