Answer 15

\[\text{Sort}\left[\left\{\frac{4}{5},\frac{7}{9},\frac{6}{7}\right\}\right]\to \left\{\frac{7}{9},\frac{4}{5},\frac{6}{7}\right\}=\{0.777778,0.8,0.857143\} \]

Answer 16

\[\frac{ 4 }{ 5 },\frac{ 7 }{ 9 }=\frac{ 36,35 }{ 45},~so~\frac{ 4 }{ 5 }>\frac{ 7 }{ 9 }\]
\[\frac{ 4 }{ 5 },\frac{ 6 }{ 7 }=\frac{ 28,30 }{ 35 },so~\frac{ 6 }{ 7 }>\frac{ 4 }{ 5 }\]
combining
\[\frac{ 6 }{ 7 }>\frac{ 4 }{ 5 }>\frac{ 7 }{ 9 }\]
in increasing order
\[\frac{ 7 }{ 9 }<\frac{ 4 }{ 5 }<\frac{ 6 }{ 7 }\]
