Answer:
8.2056 and 8.21348
Explanation:
When rounding, know the place that you want to round to. In this instance, it is the hundredth place.
Look at the digit to the right of the digit you are rounding, in this case, the hundredth place. If it is 5 or higher, round up. If it is lower than 5, round down.
8.2056
As you can see, the digit to the right of the hundredth place is 5, which means we round up. 8.2056 is rounded up to 8.21
8.21348
The digit to the right of the hundredth place is 3, which means we round down. 8.21348 is rounded down to 8.21
