Namespace trouble

chickens7 (19)
Hello ya'll, I hope someone can answer this, or atleast point me in the right direction. I've finished a program for my CS class and it worked perfect. Then I remembered we have to create out own namespace and include out class/functions in it, when I do that. I get two errors that I cannot find anywhere.
*********************************************************************
1>Source.obj : error LNK2019: unresolved external symbol "class std::basic_ostream<char,struct std::char_traits<char> > & __cdecl fraction::operator<<(class std::basic_ostream<char,struct std::char_traits<char> > &,class fraction::rational)" (??6fraction@@YAAAV?$basic_ostream@DU?$char_traits@D@std@@@std@@AAV12@Vrational@0@@Z) referenced in function _main
**************************************************************************
this horrible thing is all one error. There is another one referring to the istream. This is my header file. Any input would be MUCH appreaciated

The functions declared on lines 51 and 52 also have to be in the fraction namespace - go find where they are defined.

By the way, that's not how you pronounce (or spell) y'all ;)

Thank you for the help, I got it workin' now. By the way we get no good book learnin' in the south. I'll start with "Good day my fellow bloaks" next time :D
