How do you round off numbers?

Answer 1

You look at the ones collum then if it is a 1,2,3 or 4 you round to the nearest ten lower then the number but if it is a 5,6,7,8 or 9 you round to the nearest ten closer to the number
first,it needs to be a number like 1.45 or 3.76 or something like that.Whole numbers don't get rounded off.To round off a number,all you do is this:if it is under .50 for example...1.45,you would round it off to 1 If it is over .50 for example 3.76,you would round it off to 4
* Look at the number to the right of the number to be rounded-off: if that number is a number between 0 and four, keep the number to be rounded-off just as it is.

* If the number to the right of the number to be rounded-off has a value of 5 to 9, add 1 to the number to be rounded-off.

A slightly different answer

To round off decimals:

1. Find the place value you want (the "rounding digit") and look at the digit just to the right of it.
2. If that digit is less than 5, do not change the rounding digit but drop all digits to the right of it.
3. If that digit is greater than or equal to five, add one to the rounding digit and drop all digits to the right of it.

To round off whole numbers:

1. Find the place value you want (the "rounding digit") and look to the digit just to the right of it.
2. If that digit is less than 5, do not change the "rounding digit" but change all digits to the right of the "rounding digit" to zero.
3. If that digit is greater than or equal to 5, add one to the rounding digit and change all digits to the right of the rounding digit to zero.

If the number is 5 or greater add 1 to the number preceding it and drop the others if less than 5 just drop the numbers. i.e.

1.9536 could be 2, or it could be 1.954 if you wanted to preserve the decimal.
