Answer 1

[I don't need you]

a) ta có: \(\frac{2005}{2007}< 1\)

\(\frac{2007}{2004}>1\)

\(\Rightarrow\frac{2005}{2007}< \frac{2007}{2004}\)

Answer 2

[I don't need you]

b) ta có: \(\frac{2010}{2007}=1+\frac{3}{2007}\)

\(\frac{2007}{2004}=1+\frac{3}{2004}\)

\(\Rightarrow\frac{3}{2007}< \frac{3}{2004}\)

\(\Rightarrow1+\frac{3}{2007}< 1+\frac{3}{2004}\)

\(\Rightarrow\frac{2010}{2007}< \frac{2007}{2004}\)
