Math Misconception Test

No, 9.11 is not greater than 9.9.

Let’s break it down:

• Both numbers start with 9, so we compare the decimal parts: .11 vs. .9.
• Think of them as money: 9.11 is like $9.11, and 9.9 is like $9.90.
• Clearly, $9.90 > $9.11, so 9.9 > 9.11.

Alternatively, align the decimals:

9.11
9.90  ← we can write 9.9 as 9.90 for easier comparison

Now compare digit by digit after the decimal:

• Tenths place: 1 (from 9.11) vs. 9 (from 9.90) → 9 is greater than 1.

✅ So, 9.9 > 9.11

Final Answer: No, 9.11 is less than 9.9.
