in python ther are certain ways of creating a fraction they are


so in the above code the default values of the numerator  is 0 and denominator is 1

x = Fraction('12')
// it will be converted into 
// x = Fraction(12,1)

Operators on Fraction

all the basic operations on fractions is application such as add subtract multiply and divide and others

1/2 + 1/4 = 3/4

Fraction(1,2) + Fraction(1,4) = Fraction(3,4)

print (Fraction(18, 5) / Fraction(18, 10)) 
# returns Fraction(2, 1) 
print (Fraction(18, 5) * Fraction(16, 19)) 
# returns Fraction(288, 95) 
print (Fraction(18, 5) * Fraction(15, 36)) 
# returns Fraction(3, 2) 
print (Fraction(12, 5) ** Fraction(12, 10)) 
# returns 2.8592589556010197
