\r\n" );
document.write( "From the context, there are only two types of paper clips in this problem : red and green.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The number of red paper clips is 120, and this comprises 2/3 of all paper clips in the problem.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the green paper clips are 1/3 of all paper clips.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "But if 2/3 of all paper clips is 120, then 1/3 of all paper clips is half of 120, i.e. 120 : 2 = 60.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus the number of green paper clip is 60.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The number of green paper clips is 60.\r\n" );
