Explicación paso a paso:

$1.(\frac{64}{27}-\frac{1}{6}) (\frac{1}{4} -\frac{1}{3} x \frac{6}{5}) - \frac{1}{6} (\frac{3}{2}-\frac{1}{3})\\\\\frac{357}{162} (\frac{1}{12}x\frac{6}{5}) - \frac{1}{6} (\frac{7}{6})\\\\\frac{119}{54} x \frac{6}{60} - \frac{1}{6} x \frac{7}{6} \\\\\frac{119}{54} x \frac{1}{10} - \frac{7}{36} \\\\\frac{119}{540} - \frac{7}{36} \\\\\frac{504}{19440} = \frac{270}{9720} = \frac{135}{4860} = \frac{27}{972}$

$2.-\frac{3}{4}+ (\sqrt{\frac{25}{16}- \frac{1}{5} }) + (\frac{2}{3})^{2} x (-\frac{1}{4} )\\\\-\frac{3}{4} + (\sqrt{\frac{109}{80} } )+ \frac{4}{6} x( -\frac{1}{4})$

$3.[(-1,7) : (-2,5)]^{2}$ + $(1,1x 0,9)^{3}$

   $(0,68)^{2} + (0,99)^{3}$

    $0, 4624 + 0, 970299$

    $1, 432699$
