//return value is the numerator of the reduced form of this rational number

public int getNumerator();

//return value is the numerator of the reduced form of this rational number

//Ex: since 2/3 is the reduced form of 8/6, (8/6).getDenominator() = 3

public int getDenominator();

//return value is the double equivalent of this rational number

//Ex: (5/10).getValue() = 0.5

public double getValue();
