Decimal to Fraction Converter

The tool counts the digits after the decimal point to set the denominator as a power of ten, then makes the numerator the value times that power. For 0.75 that is 75/100, which then reduces to 3/4.

It divides the numerator and denominator by their greatest common divisor. 75 and 100 share a factor of 25, so 75/100 becomes the lowest-terms fraction 3/4. Every result is always fully reduced.

Yes. When the value is larger than one, the card shows the mixed form beside the improper fraction. 2.5 becomes the improper fraction 5/2 and the mixed number 2 1/2. Values below one just repeat the plain fraction.

Repeating decimals are approximated from only the digits you type, since the tool cannot know the pattern continues. 0.3333 becomes 3333/10000, which is close to but not exactly 1/3. Enter more threes for a closer match.

Yes. Negatives keep their sign on the numerator, so -0.6 becomes -3/5. Whole numbers like 3 are written over a denominator of one as 3/1 and labelled as a Whole number.

Up to ten places are honoured exactly. Beyond ten, the extra digits are rounded before the fraction is built, which keeps the denominator finite and the math reliable.

Any number from -1000 to 1000. The stepper buttons move in increments of 0.05, but you can type any value in that range directly, including several decimal places.

Because computers store 0.1 in binary, it is not exact internally. This tool sidesteps that by reading the digits you typed rather than the raw binary value, so 0.1 returns a clean 1/10 instead of a huge denominator.

Yes. The conversion runs entirely in your browser with no server call and no sign-in, so nothing you type is uploaded or stored.
