What is the Nearest Tenth?
The nearest tenth of a decimal number is the value one place to the right of the decimal point once it has been rounded depending on the value of the hundredths place which is located two places to the right of the decimal point.
How to Round to the Nearest Tenth
To round a decimal number to the nearest tenth, check the value of its hundredths.
If the value is equal to 5 or greater, increase the value in the tenths place by 1 and then remove all digits to the right after the first decimal place.
If the value is equal to 4 or less, simply remove all the digits to the right after the first decimal place.
For example:
- 1.25: The hundredths’ value is 5, so we round up: 1.25 → 1.3
- 3.91: The hundredths’ value is 1, so we round down: 3.91 → 3.9
- 1.8: Nothing to be done, the hundredths’ value is 0.

Round Up to the Nearest Tenth
If the hundredths’ value of a certain number is >= 5, then, according to general rounding rules, you round up to the nearest 10th.
However, the term round up to the nearest 10th means that all hundredths in between 1 and 9 are rounded up by adding 1 to the value in the tenths place, and then removing all digits to the right after the first place.
Round Down to the Nearest Tenth
If the hundredths’ value of a certain number is < 5, then, according to general rounding rules, you round down to the nearest 10th.
However, the term round down to the nearest 10th means that all hundredths in between 1 and 9 are rounded down by removing all the digits to the right after the first decimal place.
Bottom Line
Any rounded number has always the same value as the number you start with, but its value is less exact.
