tính:
C=2007/2008 x 1/2009 + 2007/2008 : 2009/2008 + 1/2008
2007/2008.1/2009 + 2007/2008 +2009/2008+1/2008

Co ai lam on giup toi voi
tính nhanh : \(\frac{2007}{2008}\times\frac{1}{2009}+\frac{2007}{2008}:\frac{2009}{2008}+\frac{1}{2008}\)
A=(2008/1+2007/2+...........+2/2007+2/2008)/(1/2+1/3+........+1/2008+1/2009)
so sánh M và N biết M=2007/2008+2008/2009 và N=2007+2008/2008+2009
so sánh M và N biết M =2007/ 2008 +2008/ 2009 và N= 2007 +2008 /2008+ 2009
