Percent to Fraction

Converting the percent to the fraction is trickier (if you want to get nice-looking result). Let's look at the example value of 37.5%.

First the calculator gets the numerator and denominator, that is, 37.5 and 100. Then both are multiplied by 10 to get rid of decimal point, i.e. to get integers, that is, 375 and 1000. Then the calculator looks for the greatest common divisor (GCD) of these two integers. Both integers are then divided by it to get smaller values. Let's do it with our example

The GCD of 375 and 1000 is 125. 375 divided by 125 equals 3, 1000 divided by 125 equals 8. The resulting fraction is 3/8.
