// Descripcion: Este programa crea objetos de tipo Fraction con valores
//              aleatorios entre 1 y 9. Los suma, resta, multiplica, divide,
//              compara, y imprime los resultados.
//              Finalmente, crea un arreglo de 10 objetos Fraction con 
//              valores aleatorios y, utilizando funciones, devuelve el 
//              resultado de la sumatoria de los elementos, y ordena el 
//              arreglo.
