Math Misconception Test

No, 9.11 is not greater than 9.9.

Here is why:

1. Look at the first decimal place (the tenths):

   • 9.9 has a 9 in the tenths spot.
   • 9.11 has a 1 in the tenths spot.
   • Since 9 is bigger than 1, 9.9 is bigger.

2. Make them the same length:

   • You can add a zero to the end of 9.9 to make it easier to compare.
   • Compare 9.90 and 9.11.
   • 9.90 is clearly larger than 9.11.
