How do i round a decimal

Answer 1

To round off decimals:

Find the place value you want (the "rounding digit") and look at the digit just to the right of it.
If that digit is less than 5, do not change the rounding digit but drop all digits to the right of it.
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:

Find the place value you want (the "rounding digit") and look to the digit just to the right of it.
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.
If that digit is greater than or equal to 5, add one to the rounding digit and change all digits to the right

Answer 2

To round a decimal number you should look at the number you are going to delete. If you have to round to the tenths you set the number of hundredth, if you have to round to the hundredth then look at the thousandth figure.

If the figure already given becomes less than 5 example: 1,2,3,4 do not do anything at all
