# Java program rational fractions

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 = ac / bd

(a/b) / (c/d) = ad / bc Hint: Check carefully to avoid divide by zero!

Design the class Fraction that can be used to manipulate fractions in a program. Among others, the class Fraction must include methods to add, subtract, multiply, and divide fractions. When you add, subtract, multiply, or divide fractions, your answer need not be in the lowest terms.

Write a Java console program using the class Fraction that performs operations on fractions. Override the method toString so that the fraction can be output using the output statement.
