### Rounding Rules

**Rule 1. ** If to the right of the digit to which you want to round the number, there is a digit:

** 0 **,
** 1 **,
** 2 **,
** 3 **,
** 4 **,

then you just need to remove all the digits to the digit to which you need to round the number.

**Examples:**

Separate the rounded digit with a **red **line, and highlight the number on the right in **green**.

Let's round the number 4.23012324 ** to a whole **

4. ** | ** ** 2 ** 3012324 โ 4

Let's round the number 4.23012324 ** to tenths **

4.2 ** | ** ** 3 ** 012324 โ 4.2

Let's round the number 4.23012324 ** to hundredths **

4.23 ** | ** ** 0 ** 12324 โ 4.23

Let's round the number 4.23012324 ** to thousandths **

4.230 ** | ** ** 1 ** 2324 โ 4.230

Let's round the number 4.23012324 ** to ten thousandths **

4.2301 ** | ** ** 2 ** 324 โ 4.2301

Let's round the number 4.230123243 ** to seven decimal places **

4.2301232**|****4**3 โ 4.2301232

** Rule 2. ** If to the right of the digit to which you want to round a number, there is a digit:

** 5 **,
** 6 **,
** 7 **,
** 8 **,
** 9 **,

then it is necessary to add 1 to the figure to which the number is rounded.

** Examples: **

Separate the rounded digit with a **red **line, and highlight the number on the right in **green**.

Let's round the number 12.56843 **to a whole**

We round the number to the nearest integer, so after decimal point we write 0 digits**.**

12**.****|****5**6843

If to the right of the red line, there is a number: 0, 1, 2, 3, 4, then you just need to remove all the numbers after the red line, and if there is a number: 5, 6, 7, 8, 9, then you also remove everything the numbers after the red line and add the number 1 to the number to the left of the red line**.**

To the right of the red line, we have the number **5**, which means we remove all the numbers to the right of the red line**.**

12** + **1 = 13

12**.**56843 โ 13

Let's round the number 985.0029 ** to thousandths **

We round the number to the nearest integer, so after decimal point we write 3 digits.**.**

985**.**002**|****9**

If to the right of the red line, there is a number: 0, 1, 2, 3, 4, then you just need to remove all the numbers after the red line, and if there is a number: 5, 6, 7, 8, 9, then you also remove everything the numbers after the red line and add the number 1 to the number to the left of the red line**.**

To the right of the red line, we have the number **9**, which means we remove all the numbers after the red line and add 1 to the number to the left of the red line**.**

2** + **1 = 3
