Rounding Whole Numbers to Nearest Tenth
3 rounded to nearest tenth
3.0
7 rounded to nearest tenth
7.0
2 rounded to nearest tenth
2.0
Whole numbers already have no decimal places, so rounding to the nearest tenth adds .0
Round to the Nearest Tenth of a Percent

What is Nearest Tenth Percent?
Nearest tenth of a percent means rounding a percentage to one decimal place. For example, 45.67% rounded to the nearest tenth of a percent becomes 45.7%.
Example: 23.456% → 23.5%
Example: 67.834% → 67.8%
Example: 89.95% → 90.0%
How to Round Percent to Nearest Tenth
- Look at the hundredths place of the percentage
- If the hundredths digit is 5 or greater, round up
- If the hundredths digit is less than 5, round down
- Keep the % symbol in your final answer
Quick Tip:
When rounding percentages, follow the same rules as regular decimal numbers, but remember to include the % symbol in your final answer.
How to Round to the Nearest Tenth
What is to the nearest tenth? Rounding to the nearest tenth means expressing a number with exactly one decimal place. Our tenths calculator uses standard mathematical rounding rules following the "round half up" convention. When you round to the nearest tenth, you look at the hundredths place - if it's 5 or greater, round up; if less than 5, round down.
What is the Nearest Tenth?
The nearest tenth refers to the closest value when a number is rounded to one decimal place. It's the first digit after the decimal point in a number.
- Tenths place: The first position after the decimal point (0.1, 0.2, 0.3, etc.)
- Hundredths place: The second position after decimal point (used to determine rounding)
- Round up: When hundredths digit is 5, 6, 7, 8, or 9
- Round down: When hundredths digit is 0, 1, 2, 3, or 4
Rounding Rules
Rule 1: Look at the next digit
Examine the digit immediately to the right of the place you're rounding to
Rule 2: If digit ≥ 5, round up
Increase the target digit by 1 if the next digit is 5, 6, 7, 8, or 9
Rule 3: If digit < 5, round down
Keep the target digit the same if the next digit is 0, 1, 2, 3, or 4
These rules ensure consistent rounding behavior across all mathematical contexts and applications, making calculations predictable and reliable.

Common Rounding Applications
Rounding is essential in many real-world applications where exact precision isn't necessary or practical. Different contexts require different levels of precision, from financial calculations that typically use two decimal places to scientific measurements that may require more.
- Financial calculations typically round to the nearest cent (hundredth)
- Test scores and grades often round to the nearest tenth or whole number
- Measurements in construction may round to the nearest eighth or sixteenth
- Scientific calculations may require rounding to significant figures

Problem Analysis:
- Original Number: 8.329
- Target: Round to nearest tenth
- Tenths place: 3 (first digit after decimal)
- Hundredths place: 2 (second digit after decimal)
- Decision digit: 2 (used to determine rounding)
Solution Steps:
- Identify tenths place: The digit 3 in 8.329
- Look at hundredths: The digit 2 in 8.329
- Apply rounding rule: Since 2 < 5, round down
- Keep tenths digit: The 3 stays the same
- Remove extra digits: Drop everything after tenths
Answer: 8.329 rounded to the nearest tenth = 8.3
Since the hundredths digit (2) is less than 5, we round down by keeping the tenths digit (3) unchanged and removing all digits after it.
190.45 → 190.5
(5 ≥ 5, round up)
28.278 → 28.3
(7 ≥ 5, round up)
6.324 → 6.3
(2 < 5, round down)
