Math Misconception Test

To determine if 9.11 is greater than 9.9, we need to compare these two decimal numbers.

We can compare them by looking at their place values from left to right.

Both numbers have the same whole number part, which is 9. So, we need to compare the decimal parts.

Let's look at the tenths place:

• 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, the number 9.11 is less than 9.9.

Alternatively, we can think of 9.9 as 9.90 to have the same number of decimal places as 9.11. Now we compare 9.11 and 9.90.

Comparing the tenths place: 1 (in 9.11) vs 9 (in 9.90). 1 is less than 9. Since the tenths digit of 9.11 is smaller than the tenths digit of 9.90, 9.11 is smaller than 9.90.

Therefore, 9.11 is not greater than 9.9. In fact, 9.11 is less than 9.9.

Answer: No, 9.11 is not greater than 9.9. 9.11 is less than 9.9.
