Fraction

The fraction class avoids the division by zero error by ensuring that the supplied denominator is not zero.

Problem Statement

Write the code for the Fraction class. The solution must meet the following requirements (new requirements are in bold):

• Should get the string representation of the fraction, as "numerator/denominator"
• Should get the numeric value of the fraction (as a real number)
• Should get the reciprocal of the fraction
• Should get the numerator and denominator
• Should add another fraction to its existing value
• Should subtract another fraction from its existing value
• Should multiply its existing value by another fraction
• Should divide its existing value by another fraction
• Should affix the sign for negative fractions onto the numerator only
• Should identify if the fraction is a proper fraction
• Should reject zero denominators

Use the following class diagram when creating your solution.

    public Fraction(int numerator, int denominator)
    {
        if (denominator == 0)
            throw new System.Exception("A fraction cannot have a denominator of zero (0)");
        Numerator = numerator;
        Denominator = denominator;
        FixSign();
    }
