# Guide to Round Decimal Numbers to the Nearest Whole Number

### What are the rules to Rounding Decimal Numbers to Whole Numbers?

- It completely relies on the value of the tenth place of the number. The tenth place of a Decimal Number is the number right after the decimal point.

**For example,** The value of the tenth place of 329.**5**47 is 5.

- If the value of the tenth place of a number is
, then the value of the place one will be increased by 1.*5 or more (greater than 5)*

**For example, **The value of the place one of 32**9**.547 is 9

If we round 329.547 to a whole number, the value will change to 330.

In the same way, rounding 2453.710 will get you the whole number 2454.

- If the value of the tenth place is 4 or less than 4, then you just need to remove everything after decimal point (including decimal symbol) and remain digits will be the whole number.

**For example,** If the decimal number is 32.**2**3902, the rounded whole number will be 32. This is because 2 is less than 5

In the same way, rounding 2959.49 will get you whole number 2959.

#### Let’s solve a few problems:

**Question:** Can you round the digit $59.90 in the whole number?

**Answer: **In $59.**9**0, the tenth place has the digit 9 that is greater than 5, so the whole number will be **$60.**

**Question: **Get the whole number of 346.5421.

**Answer: **In 346.**5**421, the tenth place has number 5. As we said earlier, if it is 5 or more, we will add 1 to the at place one. The number as Place one is 6 (34**6**.**5**421). So the whole number will be 347.

**Question: **Round the number 982.014 to a whole number.

**Answer: **The whole number will be 982 because we have 0 at the tenth place (982.**0**14), and 0 is less than 5.

**Question: **Round 521.321 to a whole number.

**Answer: **3 is less than 5 that holds the tenth position in 521.**3**21. So the answer is 521.
