11/32=0,34375;16/49=0.3265306122

vay 11/32 > 16/49

58/89=0,6516853933;36/53=0,679246283

vay 58/89 < 36/53

11/32<16/49

58/89>36/53

Ta có : \(\frac{2003.2004-1}{2003.2004}=\frac{2003.2004}{2003.2004}-\frac{1}{2003.2004}=1-\frac{1}{2003.2004}\)

            \(\frac{2004.2005-1}{2004.2005}=\frac{2004.2005}{2004.2005}-\frac{1}{2004.2005}=1-\frac{1}{2004.2005}\)

Vì \(\frac{1}{2003.2004}>\frac{1}{2004.2005}\)

Nên : \(\frac{2003.2004-1}{2003.2004}< \frac{2004.2005-1}{2004.2005}\)

câu 2003.2004 lớn hơn 2004.2005

Ta có :

 \(\frac{58}{89}< \frac{58}{87}=\frac{2}{3}=\frac{36}{54}< \frac{36}{53}\)

\(\Rightarrow\frac{58}{89}< \frac{36}{53}\) hay \(\frac{36}{53}>\frac{58}{89}\)

 theo bài ta có:

58/89<58/87=2/3=36/54<36/53

=>58/89<36/53 hay 36/53>58/89

Ta có :\(\frac{58}{89}>\frac{36}{89}\)

           \(\frac{36}{89}< \frac{36}{53}\)

=>\(\frac{58}{89}< \frac{36}{53}\)

Ta co:

\(\frac{58}{89}< \frac{58}{87}=\frac{2}{3}=\frac{36}{54}< \frac{36}{53}\)

Hay :\(\frac{58}{89}< \frac{36}{53}hay\frac{36}{53}>\frac{58}{89}\)
