Math Misconception Test

No, 9.11 is not greater than 9.9. To compare the two numbers, consider their decimal values with the same number of decimal places for clarity:

• 9.11 can be written as 9.11.
• 9.9 is equivalent to 9.90 (since adding a trailing zero does not change its value).

Now, compare digit by digit from left to right:

• Units place: Both are 9 (equal).
• Tenths place: 1 (from 9.11) vs. 9 (from 9.90). Since 9 is greater than 1, 9.90 is larger.

Therefore, 9.9 (or 9.90) is greater than 9.11. This can also be confirmed by subtraction:

• 9.9 - 9.11 = 0.79 (positive result, so 9.9 is larger).
• 9.11 - 9.9 = -0.79 (negative result, so 9.11 is smaller).

This comparison is based on standard decimal notation and numerical value, not on contextual interpretations like dates.
