Ta có: \(\frac{205}{107}>2>1\) (1)
Ta có: \(\frac{20}{23}>\frac{18.4}{23}=\frac{8}{10}\)
\(\frac{6}{10}=\frac{189}{315}<\frac{214}{315}<\frac{220.5}{315}=\frac{7}{10}<\frac{8}{10}\)
Do đó: \(1>\frac{20}{23}>\frac{7}{10}>\frac{215}{315}>0\) (2)
Ta có: \(\frac{-5}{8}=\frac{-5\cdot19}{8\cdot19}=\frac{-95}{152};\frac{-16}{19}=\frac{-16\cdot8}{19\cdot8}=\frac{-128}{152}\)
mà -95>-128
nên0> \(-\frac58>-\frac{16}{19}\) (3)
Từ (1),(2),(3) suy ra \(\frac{205}{107}>\frac{20}{23}>\frac{7}{10}>\frac{215}{315}>-\frac58>-\frac{16}{19}\)
