有没有办法在渐近中做分数？

from fractions import Fraction

# 创建分数实例
fraction1 = Fraction(1, 2)
fraction2 = Fraction(3, 4)

# 分数运算
result = fraction1 + fraction2
print(result)  # 输出: 5/4

class Fraction:
    def __init__(self, numerator, denominator):
        self.numerator = numerator
        self.denominator = denominator
        self._reduce()

    def _reduce(self):
        gcd = self._gcd(self.numerator, self.denominator)
        self.numerator //= gcd
        self.denominator //= gcd

    def _gcd(self, a, b):
        while b:
            a, b = b, a % b
        return a

    def __add__(self, other):
        new_numerator = self.numerator * other.denominator + other.numerator * self.denominator
        new_denominator = self.denominator * other.denomial
        return Fraction(new_numerator, new_denominator)

# 使用自定义分数类
fraction1 = Fraction(1, 2)
fraction2 = Fraction(3, 4)
result = fraction1 + fraction2
print(result.numerator, result.denominator)  # 输出: 5 4
