Math Misconception Test

No, 9.11 is not greater than 9.9. In fact, it's the opposite: 9.9 > 9.11.

To break it down clearly:

• 9.9 can be thought of as 9.90 for comparison purposes (adding a trailing zero doesn't change the value).
• So, we're comparing 9.90 and 9.11.
• The first differing digit is the second decimal place: 9 vs. 1.
• Since 9 > 1, 9.90 is larger.

In terms of numerical value:

• 9.9 = 990/100 = 9.9
• 9.11 = 911/100 = 9.11
• 990 > 911, so 9.9 > 9.11.

If you're thinking about string comparison (like in programming), it might depend on the method—lexicographically, "9.11" comes after "9.9" because '1' > '.' in ASCII, but that's not how numbers are compared numerically. Let me know if you meant that!
