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 place.
   • 9.11 has a 1 in the tenths place.
   • Since 9 is greater than 1, 9.9 is greater.

2. Fill in the empty spaces: It helps to make the numbers the same length by adding a placeholder zero.

   • 9.9 becomes 9.90
   • 9.11 remains 9.11
   • Now it is easy to see that 9.90 is larger than 9.11.
