From your data, either 876 or 976.

To find your number, we need to use the information provided:

You mentioned that your number has "7 tens and 6 ones". This means that the digit in the tens place is 7 and the digit in the ones place is 6.

You also mentioned that the hundreds digit is the highest of all digits. Since the tens digit is 7 and the ones digit is 6, the hundreds digit must be higher than both of them.

Therefore, the possible values for the hundreds digit are 8, 9, or any number greater than that.

Without a specific value for the hundreds digit, we cannot determine the exact number. However, we can provide a general representation:

The number can be written in the following format: [(Hundreds Digit)(Tens Digit)(Ones Digit)]

So, your number could be any of the following:
- 816
- 916
- 1016
- 1116
- 1216
- ...

Please provide the specific value for the hundreds digit if you want to determine the exact number.
