Fraction to Percent Converter
Updated: June 2026
A percent is just a fraction with a fixed denominator of 100. So converting a fraction to a percentage means rescaling it so the bottom number becomes 100 — or, more practically, turning it into a decimal and sliding the point two places. Both views give the same answer and reinforce each other.

The reliable method
Divide the numerator by the denominator to get a decimal, then multiply by 100 and add a percent sign.
3 ÷ 5 = 0.6
0.6 × 100 = 60%
Multiplying a decimal by 100 simply moves the decimal point two places to the right, so 0.6 becomes 60. That is why decimals and percents feel so interchangeable.
The equivalent-fraction view
When the denominator divides neatly into 100, you can scale directly without any division.
3/20 = 15/100 = 15%
Ask what you multiply the denominator by to reach 100, then multiply the numerator by the same amount. For quarters multiply by 25, for fifths by 20, for tenths by 10.
Fractions that give repeating percents
Just like decimals, some fractions produce a never-ending percentage.
2/3 = 0.(6) → 66.(6)% ≈ 66.7%
1/6 = 0.1(6) → 16.(6)% ≈ 16.7%
You usually round to one decimal place for a percentage, but the exact value keeps repeating. The familiar “33 and a third percent” is exactly that repeating value written as a mixed number.
A reference table
| Fraction | Decimal | Percent |
|---|---|---|
| 1/10 | 0.1 | 10% |
| 1/5 | 0.2 | 20% |
| 1/4 | 0.25 | 25% |
| 1/3 | 0.(3) | 33.3% |
| 1/2 | 0.5 | 50% |
| 3/5 | 0.6 | 60% |
| 3/4 | 0.75 | 75% |
Reading across each row makes the relationship obvious: fraction, decimal and percent are three costumes on the same number. Once you can move between any two, the third is free.
Going the other way
To reverse the process, drop the percent sign, divide by 100, and simplify. 60% becomes 60/100, which reduces to 3/5 — exactly the fraction we started with. That round trip is the quickest way to check a conversion, and it shows that fraction-to-percent and percent-to-fraction are the same skill run backwards.
Frequently asked questions
What is 3/5 as a percent?
3 divided by 5 is 0.6, and 0.6 times 100 is 60%, so 3/5 equals 60%.
How do I convert a fraction to a percentage?
Divide the numerator by the denominator, multiply by 100, and add a percent sign.
What is 1/3 as a percent?
It is 33.3% rounded, or exactly 33 and one third percent, because 1/3 is the repeating decimal 0.333…
