Math Misconception Test

No, 9.11 is not greater than 9.9.

Here is the breakdown of why:

1. Compare the tenths place: Look at the first digit after the decimal point.

   • In 9.11, the digit is 1.
   • In 9.9, the digit is 9.
   • Since 9 is greater than 1, 9.9 is the larger number.

2. Equalize the decimal places: It is often easier to compare decimals by making them the same length. You can add a zero to the end of 9.9 without changing its value:

   • 9.11
   • 9.90
   • 9.90 is clearly larger than 9.11.
