二、计算下面各题,怎样简便就怎样计算。
$\frac{5}{8}×\frac{11}{10} + \frac{3}{8}÷\frac{10}{11}$ $2 - \frac{5}{6} + \frac{1}{3} - \frac{1}{9}$ $47.5 - (6.4÷0.32 - 7.5)$
$\frac{2}{3} + \frac{12}{13}×(\frac{5}{2} - \frac{1}{3})$ $15×(\frac{1}{15} + \frac{2}{19})×19$ $(8.8 - 4)×(0.48÷1.6)$
$(\frac{1}{2} + \frac{1}{3} - \frac{1}{4})×24$ $57×8 - 406$ $(2.3 + 2.3 + 2.3 + 2.3)×2.5$
$\frac{5}{12}÷13 + \frac{1}{13}×\frac{7}{12}$ $\frac{7}{25}÷[(\frac{2}{5} + \frac{1}{10})×\frac{8}{3}]$ $4.7×3.99 + 16.01×4.7$
$5×0.75÷1.5×0.75$ $0.32×2.5×1.25$ $3.5×5.85 - 3.5 + 5.15×3.5$
$\frac{5}{8}×\frac{11}{10} + \frac{3}{8}÷\frac{10}{11}$ $2 - \frac{5}{6} + \frac{1}{3} - \frac{1}{9}$ $47.5 - (6.4÷0.32 - 7.5)$
$\frac{2}{3} + \frac{12}{13}×(\frac{5}{2} - \frac{1}{3})$ $15×(\frac{1}{15} + \frac{2}{19})×19$ $(8.8 - 4)×(0.48÷1.6)$
$(\frac{1}{2} + \frac{1}{3} - \frac{1}{4})×24$ $57×8 - 406$ $(2.3 + 2.3 + 2.3 + 2.3)×2.5$
$\frac{5}{12}÷13 + \frac{1}{13}×\frac{7}{12}$ $\frac{7}{25}÷[(\frac{2}{5} + \frac{1}{10})×\frac{8}{3}]$ $4.7×3.99 + 16.01×4.7$
$5×0.75÷1.5×0.75$ $0.32×2.5×1.25$ $3.5×5.85 - 3.5 + 5.15×3.5$
