The number 6.527314 to two decimal places is 6.53. To round a number to two decimal places, you look at the third decimal place. If it is 5 or greater, you round up the second decimal place. If it is less than 5, you leave the second decimal place as is. In this case, the third decimal place is 7, so we round up the second decimal place from 2 to 3.
The second decimal place is 5 or more, so the first decimal place increases by 1.69.6
Go to the second decimal place; if it is less than 5; round down. If it is 5 or greater, round up. So, 1.51 rounded to 1 decimal place is 1.5.
nearest tenth is first place after the decimal. Look to the second place after the decimal; if it is less than 5 you keep the original first place after the decimal; if grater than 5, you round up by adding 1 to the irst place after the decimal; in your case since the second place after decimal is 0 then the nearest tenth is 3.0
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.
