Enter a fraction like 3/4, a mixed number like 1 1/2, or a whole number, and get its decimal value. The tool also tells you whether the decimal ends cleanly or repeats forever. Everything runs in your browser.
Decimal
Shown to ten decimal places. Everything is computed locally in your browser.
How it works
A fraction is just a division: 3/4 means 3 ÷ 4 = 0.75. Mixed numbers are added to their whole part, so 1 1/2 is 1 + 0.5 = 1.5. The value is shown to up to ten decimal places, with trailing zeros trimmed.
Whether a decimal terminates depends only on the denominator in lowest terms: if its only prime factors are 2 and 5, the decimal ends (like 1/8 = 0.125); otherwise it repeats (like 1/3 = 0.3333…). The tool checks this and flags repeating results, since the displayed value is then rounded rather than exact.
Practical examples
3/4 to a decimal
3 ÷ 4 = 0.75, a clean terminating decimal. Enter 3/4 and read 0.75.
A mixed number
1 1/2 is 1.5 and 2 3/4 is 2.75. The whole part and the fraction are combined for you.
A repeating decimal
1/3 comes out as 0.3333333333 with a note that it repeats — the digits go on forever, so the shown value is rounded.
Frequently asked questions
How do I convert a fraction to a decimal?
Divide the numerator by the denominator: 3/4 is 3 ÷ 4 = 0.75. For a mixed number, convert to an improper fraction first (or just add the decimal to the whole part). The tool does this instantly.
What is 3/4 as a decimal?
0.75. Because the denominator 4 is 2×2, the decimal terminates. Similarly 1/2 is 0.5 and 1/8 is 0.125.
Why do some fractions give repeating decimals?
Because their denominator (in lowest terms) has a prime factor other than 2 or 5. 1/3, 1/6 and 1/7 all repeat, while 1/2, 1/4, 1/5 and 1/8 terminate. The tool tells you which case you have.
How does it show a repeating decimal?
As a rounded value to ten places, with a note that it repeats. It doesn’t print the repeating-digit overline notation; the note is there so you know the last digit is rounded, not exact.
Can I enter mixed numbers?
Yes. Type the whole number, a space, then the fraction: 2 3/4. It’s read as 2 + 3/4 = 2.75.
Does it handle improper fractions?
Yes. 7/4 is simply 1.75. There’s no need to convert to a mixed number first — the division works the same way.
What about negative fractions?
They convert normally: -3/4 is -0.75. Put the minus sign in front of the fraction.
How many decimal places do I get?
Up to ten, with trailing zeros removed. That’s plenty for schoolwork and everyday use; for a repeating decimal the tenth place is rounded.
Is anything I enter uploaded?
No. The division runs entirely in your browser; nothing you type is sent anywhere and analytics never receives it.
