There is no question that rounding numbers allow you to make your calculations a lot easier. The truth is that we keep rounding numbers on a daily basis, even when we are not even aware of it.
After all, just think about the time when you are at the grocery store. You know that ou need some foods but as you add them to your basket, you just keep making the math on your head to ensure that you have enough money with you. However, you don’t use the prices as they are. In most cases. when you have an item that costs $14.95, you assume that it is $15. And when you have an item that is $3.09, you assume that it is $3. Well, when you do this, you are rounding numbers.
One of the things that you need to keep in mind about rounding numbers is that you may have the need to round numbers in different ways as well as using different rounding methods.
To make things simpler, we will keep using the same default rounding mode (rounding to the nearest). Besides, in this page, you will be able to learn how to round to the nearest hundred all the numbers that you want.
How To Round To The Nearest Hundred Rules
As we just mentioned, there are different rounding modes that you can use. However, to make things simpler so that you can fully understand how to round to the nearest hundred, we will use only one: the round to the nearest mode.
With this rounding mode, and when you want to round to the nearest hundred, you need to keep in mind that:
- While rounding off to the nearest hundred, if the digit in the tens place is between 0 – 4 i.e. < 5, then the tens place is replaced by ‘0’.
- If the digit in the units place is equal to or >5, then the tens place is replaced by ‘0’ and the hundreds place is increased by 1.
Here are some examples so that you can easily understand these rules:
Let’s say that you need to round the number 142 to the nearest hundred. In this case, the number that you have in the tens place is number 2. Since 142 is nearer 100 than 200, then you will get the rounded number 100.
Here is just another example. Let’s now imagine that you have the number 486 and that you are looking to round it to the nearest hundred. As you can see, the digit in the tens place is 8, we round to the nearest multiple of hundred which is greater than the number. Hence, 486 is nearer to 500 than 400. So, 500 is the rounded number that you will get.
One last thing that you need to keep in mind is that when you are rounding numbers to the nearest hundred, you will get at least two zeros at the end of the new rounded number.

How To Round To The Nearest Hundred Manually
While it is certain that using a calculator is a lot faster when you are looking to round a number, you may not have one available when you need it. Besides, it is always a good choice to know how things are done manually since these type of knowledge can be very handy on a daily basis. So, we decided to show you a couple of practical examples so that you can easily round to the nearest hundred all the numbers that you need.
Before we start with the examples, it is worth to remember that you will need to look at the numbers located at the tenth place to see if you need to round the number up or down. So, you need to follow two rules:
- If the tens place digit is 0, 1, 2, 3, or 4, then the hundreds digit
does not change. You are rounding down.
- If the tens place digit is 5, 6, 7, 8, or 9, then the hundreds digit
increases by one. You are rounding up.
All the other digits after the hundreds digit (tens and ones digit) go to zero in both cases.
Practical Example #1: Rounding 652 To The Nearest Hundred
Let’s say that you want to round the number 652 to the nearest hundred.
The first thing that you will need to do is to determine the number that is in the hundreds position. In this case, it is the number 6. So, to know if you will need to round this digit up or down, you will need to look at the digit that is in the tens place which is on the right side of the 6. In this case, this is the number 5.
According to the rounding rules, you will need to round up. And besides, you already know that when you are rounding a number to the nearest hundred, you will get a number with at least two zeros at the end. This means that the rounded number is 700.
Practical Example #2: Rounding 3345 To The Nearest Hundred
Let’s say that you want to round the number 3345 to the nearest hundred.
The first thing that you will need to do is to determine the number that is in the hundreds position. In this case, it is the number 3. So, to know if you will need to round this digit up or down, you will need to look at the digit that is in the tens place which is on the right side of the 6. In this case, this is the number 4.
According to the rounding rules, since 4 is inferior to 5, then you will round down. And besides, you already know that when you are rounding a number to the nearest hundred, you will get a number with at least two zeros at the end. This means that the rounded number is 3300.

Practical Example #3: Rounding 7671 To The Nearest Hundred
Let’s say that you want to round the number 7671 to the nearest hundred.
The first thing that you will need to do is to determine the number that is in the hundreds position. In this case, it is the number 6. So, to know if you will need to round this digit up or down, you will need to look at the digit that is in the tens place which is on the right side of the 6. In this case, this is the number 7.
According to the rounding rules, since 7 is greater than 5, then you will round up. And besides, you already know that when you are rounding a number to the nearest hundred, you will get a number with at least two zeros at the end. This means that the rounded number is 7700.
