please check this two statements and confirm which one is accurate and provide explanation: 1) 9.9 is greater than 9.111 2) 9.111 is greater than 9.9

To determine which statement is accurate, we need to compare the two numbers \(9.9\) and \(9.111\).

1. \(9.9\)
2. \(9.111\)

First, let's express both numbers to the same number of decimal places. This makes comparison easier.

- \(9.9\) can be written as \(9.900\)
- \(9.111\) remains \(9.111\)

Now, let's compare \(9.900\) and \(9.111\) digit by digit from left to right:

- The integer part (before the decimal point) for both numbers is \(9\), so they are equal up to this point.
- The first digit after the decimal point in \(9.900\) is \(9\), while in \(9.111\) it is \(1\). Since \(9 > 1\), \(9.900 > 9.111\).

Thus, \(9.9\) (or \(9.900\)) is greater than \(9.111\).

### Conclusion:
- Statement 1) \(9.9\) is greater than \(9.111\) is accurate.
- Statement 2) \(9.111\) is greater than \(9.9\) is inaccurate.

### Explanation:
When comparing decimal numbers, we consider the value of each digit starting from the leftmost digit. By comparing \(9.900\) with \(9.111\) digit by digit, we find that \(9.900\) is indeed greater than \(9.111\).
