Rational.java

/*Write the following methods

public boolean equals(Rational other) 
– returns True if the Rational number represented by other is 
the same as the one represented by this.

public Rational mult(Rational other)
– create and return a new Rational that is the result of multiplying other and this. 
For example if the two rational numbers were 4/3 and 1/2 
the mult routine would create a new Rational number representing 4/6 (or 2/3 when reduced).

public int compareTo(Rational other)
– returns 0 if this and other represent equal rational numbers, 
a positive value if this represents a rational number greater than 
the one represented by other and a negative number is returned otherwise.
