Question

so sánh 2 phân số:

 2005/2006và200520052005/200720072007

Answer 1

\(\frac{2005}{2006}\)

\(\frac{200520052005}{200720072007}\)

\(Do2006< 200720072007\Rightarrow\frac{2005}{2006}>\frac{200520052005}{200720072007}\)

Answer 2

\(\frac{200520052005}{200720072007}=\frac{2005\times100010001}{2007\times100010001}\)

\(=\frac{2005}{2007}< \frac{2005}{2006}\)
