Is 9.11 greater than 9.9?
No, 9.11 is not greater than 9.9.
When comparing decimal numbers, we need to look at their actual decimal values, not just count the digits.
9.9 = 9.90 = 9 + 0.9 = 9 + 9/10 = 9 + 0.90 9.11 = 9 + 0.11 = 9 + 11/100
0.9 (or 0.90) equals 90/100, which is greater than 0.11 (which equals 11/100).
Therefore, 9.9 is greater than 9.11.
