9.8. The tenth place is the 2nd digit. In order to round, you have to check if the digit right after that is greater than, or equal to 5. If it's greater than or equal to 5, you make the number before that 1 higher. Example : 6.17 can be rolled up to 6.2. If lower than that, it'll just become 6.1. All other digits after 9.76 don't affect how it can be changed.
