Write this program in python 3.

Suppose we want to do arithmetic with rational numbers. We want to be able to add, subtract, multiply, and divide them and to test whether two rational numbers are equal. We can add, subtract, multiply, divide, and test equality by using the following relations: n1/d1 + n2/d2 = (n1 * d2 + n2 * d1)/(d1 * d2) n1/d1 - n2/d2 = (n1 * d2 - n2 * d1)/(d1 * d2) n1/d1 * n2/d2 = (n1 * n2)/(d1 * d2) (n1/d1)/(n2/d2) = (n1 * d2)/(d1 * n2) n1/d1 == n2/d2 if and only if n1 * d2 == n2 * d1 Define a rational number class with support for arithmetic operations (subtract, multiply, divide, and test equality methods) as follows: class Rational Number: """ Rational Numbers with support for arithmetic operations. ### your code here ####
