The insctructions say:

The constructor should store the fraction in reduced form.

a) Add two Rational numbers: The result of the addition should be stored in reduced

form.

b) Subtract two Rational numbers: The result of subtraction should be stored in reduced

form.

c) Multiply two Rational numbers: The result of the multiplication should be stored in

reduced form.

d) Divide two Rational numbers: The result of the division should be stored in reduced

form.

e) Return a String representation of Rational number in the form
