脱式计算。（怎样算简便就怎样算）
$1-(\frac{3}{5}-\frac{5}{9}\times\frac{4}{5})$ $\frac{7}{9}+\frac{9}{10}-\frac{3}{5}$
$\frac{1}{6}+\frac{1}{7}+\frac{1}{3}$ $\frac{5}{6}\times[16\div(\frac{1}{3}+\frac{1}{5})]$
$\frac{8}{15}+(\frac{5}{8}-\frac{1}{3})\div\frac{5}{6}$ $(\frac{12}{7}-\frac{3}{14}+\frac{3}{4})\div\frac{25}{49}$
$\frac{3}{7}+\frac{7}{17}+\frac{4}{7}\times\frac{17}{7}$ $\frac{4}{3}\times\frac{11}{12}+\frac{5}{12}\times\frac{4}{15}$
$\frac{1}{4}+\frac{7}{8}+\frac{7}{5}\times\frac{8}{7}$ $\frac{9}{10}\div7+\frac{1}{7}\times\frac{1}{10}$

答案： $\frac{38}{45}$ $\frac{97}{90}$ $\frac{19}{42}$ 25 $\frac{66}{35}$ $\frac{17}{7}$ $\frac{9}{7}$ $\frac{4}{3}$ $\frac{53}{8}$ $\frac{1}{7}$
