Answer:
9.92
Explanation:
When rounding you look at the number to the right of the number you are rounding to. In this case the number in the hundredth's place which we are rounding to is the 2 and the number to the right is 1. While rounding if the number is between 1 and 5 you round down and if the number is between 5 and 9 you round up. Since the number to the right, the 1, is between 1 and 5 we will round down.
I hope this helps and please don't hesitate to ask if there is anything still unclear!
