You are to write a program that requests that the user inputs a fraction of the form n/d with d nonzero. Your program then prints out the fraction in reduced form. The program then asks if the user would like to process another fraction and continues to do so as long as the user replies with Y. A fraction n/d is in reduced form provided...
