![Imagine that you want to define a class for fractional numbers, e.g., 4. Fill in the three blanks in the following code to make
it a correct definition of a Fraction class.
class Fraction:
def _init_(self, numerator, denominator):
self.n = numerator
= denominator
def
str_(self):
(str(self.n) + "/" + str(self.d))
def getnum(self):
return(self.n)
def setnum(self, numerator):
self.n = numerator
def getden(self):
return(self.d)
def setden(self, denominator):
= denominator
O self.d, return, self
O self.d, return, self.d
O return, print, self.n
O self.d, print, self.n
O n.getnum(self), return, d.getd(self)
