二、计算下面各题，怎样简便就怎样计算。
$\frac{1}{4}+\frac{8}{17}+\frac{7}{6}\div\frac{14}{9}$ $8.88\times12.5$ $57.5 - 4.25 - 15.75 + 12.5$
$12\div(1+\frac{1}{5})+50\%$ $2700 - 780\div26\times34$ $(\frac{1}{69}+\frac{2}{71})\times23+\frac{25}{71}$
$24\times(\frac{1}{2}+\frac{2}{3}-\frac{1}{8})$ $(\frac{1}{9}-\frac{1}{12})\times4\times9$ $\frac{1}{8}\times[2\div(87.5\% - 75\%)]$
$120\div32 + 12.4 + 7.6$ $(7.5 - 4)\times(0.32\div1.6)$ $\frac{1}{5}\div[\frac{1}{4}\times(\frac{1}{6}+\frac{3}{10})]$
$124\times101 - 124$ $(1 - 10\%\times8)\div\frac{1}{15}$ $\frac{5}{7}\div[32\times(1 - 37.5\%)]$
