Question

Create a class calledrational for performing arithmetic with fractions. Useinteger

variables to representthe private data of the class – thenumeratorand the

denominator. Provide a constructor that enables an object ofthis class to be

initialized when it isdeclared. Your program should store the fraction inreduced

form. For example, thefraction 2/4 would be stored in the object as 1/2.

Provide publicmemberfunctions that performeach of the following tasks:

a.Multiplyingtwo rational numbers. The result should be stored inreduced

form.

b.Dividingtwo rational numbers. The resultshould be stored in reduced

form.

c.Addingtwo rational numbers. The result should be stored inreduced

form.

d.Subtractingtwo rational numbers. The result should be stored inreduced

form.

Write a program to test yourclass.

#ifndef RATIONAL_H

the two fractions, but i don't know how since my teach ask me touse two
class object to implement the addition */

#include <iostream>
