Math Misconception Test

To determine if 9.11 is greater than 9.9, we compare the numbers digit by digit, starting from the left.

1. Compare the whole number parts: Both numbers have a whole number part of 9. They are equal.

2. Compare the tenths place (the first digit after the decimal point):

   • In 9.11, the digit in the tenths place is 1.
   • In 9.9, the digit in the tenths place is 9.

Since $1$ is less than $9$, we can conclude that $9.11$ is less than $9.9$.

Therefore, the answer is No.
