Generic operations in rational-arithmetic package

Modify the rational-arithmetic package to use generic operations, but change make-rat so that it does not attempt to reduce fractions to lowest terms. Test your system by calling make-rational on two polynomials to produce a rational function

(define p1 (make-polynomial 'x '((2 1)(0 1))))

(define p2 (make-polynomial 'x '((3 1)(0 1))))

(define rf (make-rational p2 p1))

Now add rf to itself, using add. You will observe that this addition procedure does not reduce fractions to lowest terms.

Nobody's finished this exercise yet. You'll be the first!
