In this post we will learn to round off decimal to tenth place.

## Why to Round Decimals?

Suppose below decimal number is given to you.

The given number is **too large** to write multiple times and is also **complicated for calculation**.

So instead of writing the complete number **we will take the approximate valu**e.

While **rounding decimal to tenth place**, we take the **approximate value of decimal till one number after decimal **( i.e. tenth place )

The approximate value of above decimal is;

## Method to round decimal to nearest tenth

As said earlier, we will find the approximate value of decimal till tenth place.

To do the rounding off, follow the below steps;

(a) **Check the number after the tenth place** ( i.e. hundredth place)

**If hundredth place number** ⟹ 5, 6, 7, 8, 9

If the number is 5 or greater than 5, then we will round up the tenth place number by 1

**If hundredth place number** ⟹ 0, 1, 2, 3, 4

If number is less than 5, then we will leave the tenth place number as it is.

**(b) Remove all the number after tenth place**.

Given below are solved examples for your understanding.

**Example 01**

Round off decimal to tenth place.

63.79862

Solution**Check the number in hundredth place**.

**Hundredth Place Value ⟹ 9**

We will round up the tenth place value by 1 and remove all the numbers after that.

**Hence, 63.8 is the final solution.**

**Note:**

The round off number is just an approximate value which is used to make calculation easier.

**Example 02**

Round off number to nearest tenth place.

100.049254716

**Solution**

**Check the number in hundredth place**.

**Hundredth Place Value ⟹ 4**

Here we will leave the tenth place value as it is and remove rest of the numbers beyond tenth place.

**Hence, 100.0 is the final solution.**

**Example 03**

Round off the decimal to tenth place.

6785.253

**Solution****Check the number in hundredth place**.

**Number in hundredth place ⟹ 5**

We will add up the number in tenth place by 1 and remove rest of the numbers beyond it.

**Hence, 6785.3 is the roundoff number**.

**Example 04**

Round off the below decimals to tenth place

1001. 635943

**Solution****Check the number in hundredth place**.

**Number in hundredth place ⟹ 3**

The number is less than 5, so we leave the tenth place value number as it is.

**Hence, 1001.6 is the final solution.**

**Example 05**

Round off decimals to tenth place.

1.08487

**Solution**

Check the number in hundredth place.

**Hundredth Place value ⟹ 8**

Since the number is greater than 5, we will increase tenth place value by 1.

Hence, 1.1 is the required roundoff number.
