$$1 \frac{1}{5} \cdot (2,1 \cdot \frac{9}{14} + \frac{9}{16}) = \frac{6}{5} \cdot (\frac{21}{10} \cdot \frac{9}{14} + \frac{9}{16}) = \frac{6}{5} \cdot (\frac{3}{10} \cdot \frac{9}{2} + \frac{9}{16}) = \frac{6}{5} \cdot (\frac{27}{20} + \frac{9}{16}) = \frac{6}{5} \cdot (\frac{27 \cdot 4}{20 \cdot 4} + \frac{9 \cdot 5}{16 \cdot 5}) = \frac{6}{5} \cdot (\frac{108}{80} + \frac{45}{80}) = \frac{6}{5} \cdot \frac{108 + 45}{80} = \frac{6}{5} \cdot \frac{153}{80} = \frac{3}{5} \cdot \frac{153}{40} = \frac{459}{200}$$
Ответ: $$\frac{459}{200}$$
