What is 0.76133 to one decimal place?

0.8To round to 1 decimal place we look at the second digit after the decimal point and ask if it is equal to or greater than 5. If it is we round the first digit up (add 1 to it). If not we round down (the first digit remains the same).Here the second digit is "6" and so we round the first digit up to "8".

How do your A to the nearest tenth?

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.
