紧急求助:2003÷2003又2003/2004+1/2005紧急求助:2003÷2003又2003/2004+1/2005紧急求助:2003÷2003又2003/2004+1/20052003又20

紧急求助:2003÷2003又2003/2004+1/2005
紧急求助:2003÷2003又2003/2004+1/2005

紧急求助:2003÷2003又2003/2004+1/2005
2003又2003/2004 = [(2003*2004)+2003]/2004=2003*2005/2004
2003÷2003又2003/2004,即2003÷(2003*2005/2004)=2003*2004/2005*2004=2004/2005
所以2003÷2003又2003/2004+1/2005 =2004/2005+1/2005=1

=2003/(2003+2003/2004)+1/2005=2004/2005+1/2005=1

2003÷2003又2003/2004+1/2005
=2003*2004/2003*2005+1/2005
=2004/2005+1/2005
=1

2003/(2003+2003/2004)+1/2005
=2003/2003(1+1/2004)+1/2005
=2004/2005+1/2005
=1
