Fraction to Decimal
Turn any fraction into its exact decimal.
How to use
- 1 Type a fraction such as 3/4, an improper fraction like 7/2, or a mixed number like 1 1/2.
- 2 Read the decimal value, which marks repeating digits in parentheses.
- 3 Check the reduced fraction and numeric approximation below it.
- 4 Copy the decimal for use elsewhere.
About Fraction to Decimal
The Fraction to Decimal converter turns a fraction into its decimal value and tells you whether that decimal terminates or repeats.
Enter a proper fraction like 3/4, an improper fraction like 7/2, or a mixed number written as a whole number, a space and a fraction such as 1 1/2, and the tool reduces it, divides it out and shows the result instantly.
Negative values are fully supported, so -2 1/4 converts just as cleanly as its positive counterpart.
What sets this converter apart is its exactness.
Rather than rounding to a fixed number of places, it performs true long division and watches for a remainder it has seen before.
When it finds one, it knows the decimal repeats and marks the repeating block in parentheses — so 1/3 becomes 0.(3) and 1/6 becomes 0.1(6), making the pattern unmistakable.
For fractions that divide evenly, you get the precise terminating decimal with no spurious trailing digits.
Alongside the decimal you also see the fraction reduced to lowest terms and a plain numeric approximation handy for spreadsheets or code.
Everything is computed locally in your browser using ordinary integer arithmetic.
Nothing is uploaded, logged or stored, the tool works offline once loaded, and it makes a reliable companion for homework, recipes, measurements and engineering tasks alike.
FAQ
How are repeating decimals shown?
The repeating block of digits is wrapped in parentheses. For example 1/3 is shown as 0.(3) and 1/7 as 0.(142857), meaning that group repeats forever.
Can I enter mixed numbers?
Yes. Write the whole number, a space, then the fraction, for example "1 1/2" or "-2 1/4". The tool combines them into a single decimal.
What happens if the denominator is zero?
Division by zero is undefined, so the tool shows a clear error asking you to enter a non-zero denominator.
