Question #332746

Machine 8


Reducing Fraction to Lowest Term


Create a Python script that will reduce an input fraction to its lowest term.


Program Requirements:


1. Define a function that will check first if the input fraction is a VALID fraction.


2. Define a function that will split a VALID fraction and return a list that consists the numerator and denominator.


3. Define a function that will accept two parameters (numerator and denominator to determine the greatest common divisor.


4. Define a function that will accept two parameters (numerator, denominator) and will return the reduced fraction.


Sample Output:


Input a fraction: 4/6


Reduced fraction is 2/3

    a = int(you_fraction_split[0])
    b = int(you_fraction_split[1])

    print("Reduce fraction is " + reduce_fraction(a, b))


if __name__ == '__main__':
