Rounding to the nearest hundredth is a useful rounding skill in math, finance, measuring, science, and other situations. If a decimal number contains many digits after the decimal point, then rounding can help to make a number easier to understand and use.
Fortunately, the process of rounding to the nearest hundredth is quite easy to learn. All you have to do is to find the hundredth position and the number after it. Here you will find information about how to round to the nearest hundredth, some examples of rounding to the nearest hundredth and how to use the calculator for checking your result.
What Is the Nearest Hundredth?
Rounding to the nearest hundredth is a useful rounding skill in math, finance, measuring, science, and other situations. If a decimal number contains many digits after the decimal point, then rounding can help to make a number easier to understand and use.
Fortunately, the process of rounding to the nearest hundredth is quite easy to learn. All you have to do is to find the hundredth position and the number after it. Here you will find information about how to round to the nearest hundredth, some examples of rounding to the nearest hundredth and how to use the calculator for checking your result.
What Is the Nearest Hundredth?
The hundredth position is the second one from the decimal point.
For instance, consider the number 24.376:
- 3 is the tenth position.
- 7 is the hundredth position.
- 6 is the thousandth position.
So, the number looks like this:
24.376
| Decimal Place | Digit |
|---|---|
| Ones | 4 |
| Tenths | 3 |
| Hundredths | 7 |
| Thousandths | 6 |
When you round to the nearest hundredth, your final answer should normally have two digits after the decimal point.
For example:
24.376 → 24.38
What Is the Nearest Hundredth?
There are four basic steps in rounding to the nearest hundredth.
Step 1: Locate the Hundredths Digit
Locate the second digit after the decimal point.
For example:
7.456
Digits after the decimal are:
4 – tenth
5 – hundredth
6 – thousandth
Therefore, the hundredth digit is 5.
Step 2: Locate the Thousandths Digit
This time locate the digit on the right-hand side of the hundredth digit.
In the above figure, 7.456, the thousandths digit is 6.
Step 3: Rounding Rule
Remember this simple rule:
If the thousandths digit is 5, 6, 7, 8, or 9, add 1 to the hundredth digit.
If the thousandths digit is 0, 1, 2, 3, or 4, do not change the hundredth digit.
Step 4: Delete Unnecessary Digits
After rounding off, remove all digits following the hundredth digit.
For example:
7.456 -> 7.46
As the thousandth digit is 6, the 5 at the hundredths place becomes 6.
Round to Nearest Hundredth: Examples
Here are some examples for your guidance.
Example 1: 5.234
The task is to round off the number to the nearest hundredth place.
Hundredth digit = 3
Thousandth digit = 4
As 4 < 5, the hundredth place remains unchanged
Answer: 5.23
Example 2: 7.456
Hundredth digit = 5
Thousandth digit = 6
As 6 > 5, the hundredth place is incremented by 1
Answer: 7.46
Round to Nearest Hundredth: Examples
For normal classroom rounding, if the digit right next to the one being asked about is 5 or larger, round up.
Example:
6.125 → 6.13
In this case:
Hundredths digit = 2
Thousandths digit = 5
Since 5 means round up, 2 becomes 3
Thus: 6.125 rounded to the nearest hundredth = 6.13
Rounding to the Nearest Hundredth Table
| Original Number | Thousandths Digit | Rounded Answer |
|---|---|---|
| 2.341 | 1 | 2.34 |
| 4.256 | 6 | 4.26 |
| 5.432 | 2 | 5.43 |
| 7.895 | 5 | 7.90 |
| 8.127 | 7 | 8.13 |
| 10.564 | 4 | 10.56 |
| 12.678 | 8 | 12.68 |
| 15.999 | 9 | 16.00 |
Important: 7.895 becomes 7.90 when rounded to the nearest hundredth. The extra zero is important because the answer is expressed to two decimal places.
How to Use a Round to the Nearest Hundredth Calculator
A rounded to the nearest hundredth calculator may come handy when trying to get the rounded form of a decimal number.
The basic procedure is as follows:
Type the decimal number.
Choose the nearest hundredth alternative, if provided.
Click on the calculate or round button.
See the results.
Apply the rounding rules to confirm the answer.
For instance, if you input:
18.736
The calculator will recognize that the hundredth place is 3 and the thousandth place is 6.
Since 6 is bigger than 5:
18.736 → 18.74
You may use the calculator when trying to check your answers, particularly long decimal numbers.
Common Mistakes When You Round to the Nearest Hundredth
Here are some errors that students tend to commit.
Rounding Off to the Wrong Digit
In rounding off to the nearest hundredths, avoid rounding off using the tenths digit. Use the thousandths digit.
Failing to Keep Only Two Decimal Places
Unless specified otherwise, your answer should have two places after the decimal.
Example:
4.678 → 4.68
Not 4.678.
Failing to Round Up Your Answers
If the thousandths digit is 5 or more, the hundredths digit should be rounded up.
Example: 3.456 → 3.46
Failing to Recognize the Hundreds Place
Remember that:
Tenths → first digit after decimal
Hundreds → second digit
Thousands → third digit
Conclusion
If one knows how to round to the nearest hundredth, it becomes easier to deal with decimals. To round a decimal to the nearest hundredth, all that needs to be done is to find out what the hundredths digit is and then use the rounding rule, based on the value of the thousandths digit.
Keep in mind:
0 – 4 → The hundredths digit stays the same.
5 – 9 → The hundredths digit increases by 1.
Rounding to the nearest hundredth becomes easy after some practice. Using a round to the nearest hundredth calculator will also be helpful when dealing with longer decimals.
