Answer 2

Rounding is simple:

• If the previous digit is 5-9, round the number to the left of it up a number. If it is 4-0, leave the number to the left of it as it is.

For 82.98, we can round 82 to 83, since 82 is the whole number and the previous digit is 9 (so we round up).

For 169.645, we scratch off 45. Since 6 is in the tenth's place and the previous digit of it is 4, we leave it at 169.64.
