## Rounding Large Numbers – Definition

It is difficult to Round Off Large or Complex Numbers. The Roundoff numbers will not give the exact value. The concept of Rounding Numbers will help the students to do mental math calculations. If the number nearest to the place is 5 or greater than 5, then the number is rounded up. If the number nearest to the place is 5 or less than 5, then the number is rounded down.

### How to Round Big Numbers?

There are some steps to round off the large numbers. The below steps will help you to write the numbers nearest to hundred thousand, million, etc.

1. If the number you are rounding off is greater than 5 then you have to round the given number up.

2. If the number you are rounding off is less than 5 then you have to round the given number down.

3. All the numbers to the right of the place are rounding off to become zero.

### Rounding Off to the Nearest Ten Thousand

If the digit in the thousands place is less than 5 then round to the nearest multiple of ten thousand which is smaller than the given value. If the digit in the thousands place in a number is greater than 5 such as 5, 6, 7, 8, 9 then round the given number to the nearest multiple of ten thousand.

**Example:**

Round off 46238 to the nearest ten thousand.

**Solution:**

The number in the thousands place is greater than 5.

So, we have to round off the number up.

Thus the number 46238 to the nearest ten thousand is 50000.

### Rounding Off to the Nearest Hundred Thousand (100,000)

If the digit in the ten thousand place is less than 5 such as 4, 3, 2, 1, or 0, then we have to round the given number to the nearest multiple of hundred thousand. If the digit in the ten thousand places is greater than 5 such as 6, 7, 8, 9 then you have to round the given number to the nearest multiple of a hundred thousand. Therefore to round off the numbers to the nearest hundred thousand we have to see the ten thousand place.

**Example:**

Round off 285648 to the nearest hundred thousand.

**Solution:**

Here the ten thousand place is greater than 5, so we have to round up the given to the hundred thousand.

The number 285648 to the nearest hundred thousand is 300000.

### Rounding Off to the Nearest Million (1,000,000)

If the digit in the hundred thousand’s place is less than 5 that is 4, 3, 2, 1, or 0 then we have to round the given value to the nearest multiple of one million.

If the given digit in the hundred thousand place is greater than 5 such as 5, 6, 7, 9 then we have to round off the given value to the nearest multiple of one million. So, in order to round larger number that is nearest million we have to go through hundred thousand place.

**Example:**

Round off 4286261 to the nearest million.

**Solution:**

Now we have to round off the given number to the nearest million.

First, you have to check the hundred thousand place.

The number in the hundred thousand place is 2.

Here 2 is less than 5.

So, rounding 4286261 is 4000000.

### Rounding the Given Number to the Nearest Ten Million (10,000,000)

If the number in the one million place is less than 5 such as 4, 3, 2, 1, or 0 then you have to round the given number to the nearest multiple of 10 million which is less than the given number.

If the number in one million place is greater than 5 such as 6, 7, 8, 9 then we have to round off the given number to the nearest multiple of 10 million which is greater than the given number.

So, to round off the given number to the nearest ten million we have to check out the one million place.

**Example:**

Round off 17364134 to the nearest ten million.

**Solution:**

Given,

17364134

we have to check the number in one million place.

The digit in the one million place is 7 which is greater than 5.

So, the estimated or rounded number will be greater than the given number.

So, the number 17364134 nearest to ten million is 20000000.

### Examples on Rounding Large Numbers

Go through the below examples and know-how to round larger numbers.

**Example 1.**

Round the number 71,124 to the nearest ten thousand.

**Solution:**

Given number 71,124.

To find the nearest ten thousand we have to check the thousands place.

If the digit in the thousands place is less than 5 then round to the nearest multiple of ten thousand which is smaller than the given value.

If the digit in the thousands place in a number is greater than 5 such as 5, 6, 7, 8, 9 then round the given number to the nearest multiple of ten thousand.

The digit in the thousands place is 1.

So, the number 71,124 to the nearest ten thousand is 70,000.

**Example 2.**

Round the number 89,624 to the nearest ten thousand.

**Solution:**

Given number 89,624.

To find the nearest ten thousand we have to check the thousands place.

If the digit in the thousands place is less than 5 then round to the nearest multiple of ten thousand which is smaller than the given value.

If the digit in the thousands place in a number is greater than 5 such as 5, 6, 7, 8, 9 then round the given number to the nearest multiple of ten thousand.

The digit in the thousands place is 1.

So, the number 89,624 to the nearest ten thousand is 90,000.

**Example 3.**

Round off the number 435,343 to the nearest hundred thousand place.

**Solution:**

Given the number 435,343.

If the digit in the ten thousand place is less than 5 such as 4, 3, 2, 1, or 0, then we have to round the given number to the nearest multiple of hundred thousand.

If the digit in the ten thousand places is greater than 5 such as 6, 7, 8, 9 then you have to round the given number to the nearest multiple of a hundred thousand. Therefore to round off the numbers to the nearest hundred thousand we have to see the ten thousand place.

Here 3 is less than 5 so the round off number will be less than the given number.

So, the answer is 400,000.

**Example 4.**

Round off the number 5,838,520 to the nearest million place.

**Solution:**

Now we have to round off the given number to the nearest million.

First, you have to check the hundred thousand place.

The number in the hundred thousand place is 2.

Here 2 is less than 5.

So, rounding 5,838,520 is 6,000,000.

**Example 5.**

Round off the number 51,514,311 to the nearest ten million place.

**Solution:**

we have to check the number in one million place.

The digit in the one million place is 7 which is greater than 5.

So, the estimated or rounded number will be greater than the given number.

So, the number 51,514,311 nearest to ten million is 50000000.

### FAQs on Rounding Large Numbers

**1. How do you round millions to the nearest thousand?**

To round a number to the nearest 1000, look at the hundreds digit. If the hundreds digit is 5 or more, round up. If the hundreds digit is 4 or less, round down.

**2. How do you round numbers to the nearest 10000?**

The rule for rounding to the nearest ten thousand is to look at the last four digits. If the last four digits are 5,000 or greater, then we round our ten thousands digit up, and if it is less than 5,000, then we keep our ten thousands digit the same.

**3. How do you round big numbers to the nearest whole number?**

To round a number to the nearest whole number, you have to look at the first digit after the decimal point. If this digit is less than 5 we don’t have to do anything, but if the digit is 5 or greater we must round up.
