# How to Round to the Nearest Whole Number?

We need to round off the given whole number to its nearest tens, hundreds or thousands with aim to estimate the nearest value. Now let us see How to Round to the Nearest Whole Number.
We will start with rounding of the number to the nearest 10. Here we must remember that digit at ones place is zero. Another thing we need to remember when we are rounding the whole number to the nearest tens is that digit at ones place is less than 5, then it simply changes to zero and in case it is equal or greater than 5, then we will add 10 to the given number and subtract the digit at ones place.

It will be clear with following example:

Let us consider the number 247. Here we observe that digit at ones place is 7, so we will add 10 to the given number and subtract 7 (which is at the ones place).

So number in the rounded form becomes: 247 + 10 – 7 = 250,

On the other hand if we take number 1463. So here digit at ones place is 3, which is less than 5. Thus we will subtract the digit at ones place (i.e. 3).

Round (1463) = 1463 = 1463 – 3 = 1460.

Similarly to round off the given whole number to nearest 100, we will look at last two digits of the given number. We will check if last two digits of the number is less than 50, then we will simply subtract them from the given number. On the other hand if we observe that last two digits are equal or > 50, then we subtract two digits and add 100 to the given number.
