Homework Help Please

I ran across some errors in this cpp program I had to write for school, and I can't figure out what to do...my instructions are below; any help or advice is greatly appreciated!

Rational fractions are of the form a / b, in which 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, in which c/d ≠ 0
Fractions are compared as follows: a / b op c / d if ad op bc, in which op is any of the relational operations. For example, a / b < c / d if ad < bc.

Design a class fractionType that performs the arithmetic and relational operations on fractions. Overload the arithmetic and relational operators so that the appropriate symbols can be used to perform the operation. Also, overload the stream insertion and stream extraction operators for easy input and output.

Write the class fractionType, that performs operations on fractions. Among other things, test the following: Suppose x, y, and z are objects of type fractionType. If the input is 2/3, the statement:

cin >> x;
should store 2/3 in x. The statement:

cout << x + y << endl;
should output the value of x + y in fraction form. The statement:

z = x + y;
should store the sum of x and y in z in fraction form. Your answer need not be in the lowest terms.

Why did you comment this #include "fractionType.h".Main can not see any of the objects type fractionType because it isn't included.

Do you see "fractionType" defined there?
Do you see definition of "fractionType" included there?
I completely overlooked this issue...thank you all very much!
