A ) 2005/2007 va 2007 /2009
B) 2010/2007 va 2007 / 2004
Bài 1: So sanh biểu thức A với 4 biết :A= 2010 /2009+ 2011 /2010+ 2012/ 2011+ 2009/2012
so sanh:1/101+1/102+..........+2009/2010+1/200 voi 5/8
So sánh A và B biết : A=2009*2009+2008/2009*2009+2009 va B=2009*2009+2009/2009*2009+2010
So sánh 2 phân số:
A=2009*2009+2008/2009*2009+2009 va B=2009*2009+2009/2009*2009+2010
so sanh 2009/2011 va 19/21
so sanh 201050+1/201049+1 va 201049+1/201048+1
