Percent to Fraction

Converting a percentage to a fraction is a bit more complicated if you want a simplified result. Let's take the example of 37.5%.

First, the calculator takes the numerator and denominator (37.5 and 100, respectively) and multiplies both by 10 to eliminate the decimal point and obtain whole numbers: 375 and 1000. Then, the calculator finds the greatest common divisor (GCD) of these two integers. Both integers are then divided by the GCD to simplify the fraction. Here's how to do it with our example:

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