Learn how to round percentages to the nearest tenth with examples
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%
Quick Tip:
When rounding percentages, follow the same rules as regular decimal numbers, but remember to include the % symbol in your final answer.
Many homework questions combine percentages with rounding. Here are step-by-step examples like "180.4 is what percent of 128? Round to the nearest tenth." and "find 27.4% of 424. Round to the nearest tenth."
Answer: 180.4 is about 140.9% of 128 when rounded to the nearest tenth of a percent.
Answer: 60.9 is about 95.2% of 64 to the nearest tenth.
Answer: 27.4% of 424 is about 116.2 when rounded 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.
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.
Examine the digit immediately to the right of the place you're rounding to
Increase the target digit by 1 if the next digit is 5, 6, 7, 8, or 9
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.

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.

Suppose you have a right triangle with angle A = 31° and adjacent side length 4.5, and you want to find the opposite side x using the tangent function. The problem might say:
"Solve for x. Round your answer to the nearest tenth, if necessary."
Answer: x ≈ 2.7 units to the nearest tenth.
Imagine a triangle problem where you use similar triangles and get the equation 9 ÷ x = 3 ÷ 2. Solve for x and then round to the nearest tenth.
Answer: x = 6.0 to the nearest tenth.
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)
