a)-22/45 va -51/101
b)so sanh A=\(\frac{^{2009^{2009}}+1}{^{2009^{20010}}+1}\)va B=\(\frac{2009^{2010}-2}{2009^{2011}-2}\)

So Sanh Hai Phan So Sau:
\(A=\frac{2014}{2015}-\frac{2015}{2016}+\frac{2016}{2017}-\frac{2017}{2018}\) VA \(B=-\frac{1}{2014.2015}-\frac{1}{2016.2017}\)
So sanh : A = \(-\frac{2012}{4025}\) va B = \(-\frac{1999}{3997}\)
So sanh:
a,\(\frac{-47}{83}va\frac{65}{-73}\)
b,\(\frac{-176}{527}va\frac{-92}{277}\)
c,\(\frac{-45}{59}va\frac{-71}{96}\)
d,\(\frac{-201}{101}va\frac{-149}{75}\)
