Math Misconception Test

No, 9.11 is not greater than 9.9.

Here's how to compare them:

• Compare the whole numbers: Both have 9.
• Compare the first digit after the decimal point (the tenths place):
  • In 9.11, the digit is 1.
  • In 9.9, the digit is 9.

Since 1 is less than 9, 9.11 is less than 9.9.

You can also think of 9.9 as 9.90. Then comparing 9.11 and 9.90:

• 9.11 (one hundred eleven)
• 9.90 (nine hundred ninety)

Clearly, 9.11 is smaller.
