How do your A to the nearest tenth?

Answer 1

You round your answer to one decimal place.So if the digit in the second decimal place is more than 5 the digit in the first place is increased by 1.

and if the digit in the second decimal place is less than 5 the digit in the first place is left unchanged.

If the digit in the second place is 5 then you either go to the next decimal place. It it is 1 then you round up, if not then you round down.

If the digit in the second decimal place is 5 and there are no more digits then many schools incorrectly advise you to round up. This is incorrect because it introduces a bias. The IEEE approved solution is the "round-to-even": round the number up or down so that the last digit remaining in the number is even.
