Rational fractions are of the form a / b, where a and b are integers and b != 0. In this exercise, by "fractions" we mean rational fractions. Suppose a / b and c / d are fractions. Arithmetic operations on fractions are defined by the following rules: a/b + c/d = (ad + bc) / bd a/b - c/d = (ad - bc) / bd a/b * c/d =
