Comment ça marche

The tool writes the decimal over a power of ten matching its decimal places (0.75 becomes 75/100), then reduces the fraction to lowest terms by dividing both parts by their greatest common divisor (giving 3/4). Repeating decimals use a different algebraic method to find the exact fraction. The result is the simplest equivalent fraction.
