How the Fraction Subtraction Calculator Works
Result (decimal) = (a * d - c * b) / (b * d)The formula used by the calculator is result = (a * d - c * b) / (b * d), where a and b are the numerator and denominator of the first fraction, and c and d are those of the second fraction. For example, if you subtract 1/2 from 3/4, the calculation would be (3 * 2 - 1 * 4) / (2 * 2) = (6 - 4) / 4 = 2 / 4 = 0.5.
