Write a program for the fraction calculator shown in the figure below. After the numerators and denominators of the two fractions to the left of the equal sign are placed in the four text boxes, one of four operations should be clicked on. The result appears to the right of the equal sign. The program should use a calculator class, which contains three members of the type Fraction discussed in Exercise 28 of Section 11.1. Note: In the figure below, the fraction bars are very short list boxes.

BEFORE FINISHING THIS PAGE REMOVE THE REFERENCE TO EXERCISE 28 ABOVE.  ALSO CHANGE THE PICTURE TO REFLECT * AND /.
