document.write( "Sumalee makes  \"1%2F15\"  of the job per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Cody  makes  \"1%2F10\"  of the job per minute.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Working together, they make  \"1%2F15\" + \"1%2F10\" = \"2%2F30+%2B+3%2F30\" = \"5%2F30\" = \"1%2F6\" of the job per minute.\r\n" );

document.write( "\r\n" );
document.write( "Hence, it will take 6 minutes for both to complete the job working together.\r\n" );
