Question

In python, I am working on a program and I feel like this is an easy problem but I haven't been able to solve it. At the end is a print statement. I wanted to do one for each of the answers, however I keep rinning into syntax errors and type errors.

Any help is appreciated if you can tell me why and show me how it should look. The example I left is the (x+y) in the def main() section.

def gcd(m,n):

while m%n != 0:
oldm = m
oldn = n

m = oldn
n = oldm%oldn
return n

class Fraction:
def __init__(self,top,bottom):
self.num = top
self.den = bottom

def __str__(self):
return str(self.num)+"/"+str(self.den)

def __add__(self,otherfraction):
newnum = self.num*otherfraction.den +
self.den*otherfraction.num
newden = self.den * otherfraction.den
common = gcd(newnum,newden)
return Fraction(newnum//common,newden//common)
  
def __eq__(self, other):
firstnum = self.num * other.den
secondnum = other.num * self.den

def __sub__(self, otherfraction):
newnum = self.num * otherfraction.den - self.den * otherfraction.num
newden = self.den * otherfraction.den
common = gcd(newnum,newden)
  
return Fraction(newnum//common, newden//common)

def __mul__(self, otherfraction):
newnum = self.num * otherfraction.num
newden = self.den * otherfraction.den
common = gcd(newnum,newden)

return Fraction(newnum//common, newden//common)

def __truediv__(self, otherfraction):
newnum = self.num * otherfraction.den
newden = self.den * otherfraction.num
common = gcd(newnum, newden)

return Fraction(newnum//common, newden//common)
  
return firstnum == secondnum

def main():
x = Fraction(1,2)
y = Fraction(2,3)
print("The sum is:"(x+y))
print(x == y)
print(y - x)
print(x * y)
print(y/x)

Explanation / Answer
