Direct answer
To round to the nearest tenth, look at the hundredths digit (the second digit after the decimal point). If it is 5–9, add 1 to the tenths digit; if it is 0–4, keep it. Then drop the rest. 8.329 → 8.3, 36.89753 → 36.9, 1.965 → 2.0.
Last updated: September 30, 2026. Works with whole numbers, percents, fractions, division, and square roots. Short version: how to round to the nearest tenth. Also: 14 ÷ 9 and √30 · tenth vs ten.
yellow = tenths digit, red = hundredths digit that decides. Only that one digit matters.

The nearest tenth is the closest number with exactly one digit after the decimal point — a multiple of 0.1, such as 36.8, 36.9, or 37.0. “Round to the nearest tenth,” “round to tenths,” “nearest 10th,” and “round to one decimal place” all ask for the same thing.
| Tens | Ones | . | Tenths | Hundredths | Thousandths | Ten-thousandths | Hundred-thousandths |
|---|---|---|---|---|---|---|---|
| 3 | 6 | . | 8 | 9 | 7 | 5 | 3 |
The tenths digit is 8 and the hundredths digit is 9. Because 9 ≥ 5, the 8 rounds up: 36.89753 → 36.9. The digits 7, 5, and 3 never matter.
Find the tenths digit
It is the first digit after the decimal point. In 36.89753 the tenths digit is 8.
Look at the hundredths digit
It is the second digit after the decimal point. In 36.89753 it is 9. This is the only digit that decides.
Round up or keep
If the hundredths digit is 5 or more, add 1 to the tenths digit (a 9 becomes 0 and carries 1). If it is 0–4, keep the tenths digit.
Drop the rest and keep one decimal place
Remove every digit after the tenths place. Keep a trailing zero: 14.96 → 15.0, and 8 → 8.0.
Round up: hundredths digit 5–9
190.45 → 190.5 · 652.77 → 652.8 · 14.96 → 15.0
Keep: hundredths digit 0–4
8.329 → 8.3 · 6.7499 → 6.7 · 8.24 → 8.2

Rounding from the right in stages (6.7499 → 6.750 → 6.75 → 6.8) is wrong. Only the hundredths digit, 4, decides, so the answer is 6.7.
The 9 becomes 0 and 1 carries into the ones place. 793.988 → 794.0 and 9.96 → 10.0 work the same way.
Cutting off digits is not rounding. The hundredths digit is 7, so the tenths digit goes up.
“15” reads as rounded to the nearest whole number. Keep one decimal place. A whole number such as 8 becomes 8.0.
“Nearest tenth” is one decimal place: 7,445 → 7,445.0. “Nearest ten” is a whole number ending in 0: 7,445 → 7,450.
Work out the value to at least two decimal places first, then apply the hundredths rule. You can type these straight into the calculator.

“Approximate 3√30 to the nearest tenth” with choices like 3.1, 3.9, 2.9, 5.5 is asking for the cube root: ∛30 ≈ 3.1. Written as 3 × √30 it is 16.4.

“Find x. Round to the nearest tenth of a degree.” For a right triangle with opposite side 3 and adjacent side 4, x = tan⁻¹(3 ÷ 4) ≈ 36.8699°, so x ≈ 36.9°. Keep full precision until the last step.
Odometers and trip logs use tenths. 12.46 mi → 12.5 mi; 3.04 mi → 3.0 mi. A whole distance like 89 miles is 89.0 miles to the nearest tenth.

It uses the rule taught in school: a deciding digit of 5 rounds away from zero (190.45 → 190.5, −2.25 → -2.3). It rounds the decimal digits you type, not a binary approximation, so 2.675 → 2.68 at the hundredth — spreadsheets and programming languages sometimes show 2.67 for that. Some finance and computing contexts use round-half-to-even (banker’s rounding), the default in IEEE 754 binary floating point; that only changes answers on an exact 5 with nothing after it.
