Create a fraction calculator program, Programming Languages

You need to create a Fraction calculator program.You need to create a Fraction class to represent fraction objects and a FractionCalculator class that will perform operations on fractions. Make sure you use input validation, so your program doesn't crash.

Requirements for Class Components:

• You need to create a Fraction class that stores information regarding fractions.

o The class should have private instance fields for this class called numerator and denominator.

o You need properties to get/set these values.
 Name them Numerator and Denominator.
o The class needs a constructor that accepts two strings that are used to construct a fraction object: one for the numerator, and one for the denominator.

o The class needs a constructor that accepts two integers that are used to construct a fraction object.

o You need an Equals() method that returns true when a fraction passed into the method is equal to the fraction object the method was called upon.

 Example: If frac1.equals(frac2) Then ...

o You need a ToString() method that returns a string representation of a fraction.

For example, a fraction with a numerator of 5 and a denominator of 6 would return "5/6" when the ToString method is called.

• You need to create a FractionCalculator class will be responsible for working with two fractions.

o This class should be used to perform addition, subtraction, multiplication, and divide.

o The Add, Subtract, Multiply, and Divide methods should take two fractions objects as input and return a new fraction which is the result of the operation that was performed on the two input fractions.

o This class needs a Swap() method that will accept two fraction objects and swap them.

o This class needs an Invert() method that will accept a single fraction object and swap the numerator and denominator.
 For example, fraction "3/4" becomes "4/3"

o Try creating a Reduce() method to simply fractions for an extra credit challenge.

 Hint: you will need recursion and the Euclidean Algorithm.

User InterfaceRequirements:

• You need to create a form that allows the user to enter two fractions, perform a specific operation (+, -, *, /, swap, and invert), and display the results.

• Display clear instructions to the user where necessary.

Fraction Help:

Adding fractions: a/b + c/d
(ad + bc) / bd

Subtracting fractions: a/b - c/d
(ad - bc) / bd

Multiplying fractions: a/b * c/d
(a * c) / (b * d)

Dividing fractions: (a/b) / (c/d)
(a * d) / (b * c)
