1. 直接写出得数。（建议 2 分钟完成）
$30\times\frac{5}{6}=$ $6\div\frac{3}{4}=$ $\frac{4}{5}\div\frac{8}{15}=$ $\frac{11}{17}\div22=$
$\frac{5}{6}\div30=$ $\frac{3}{4}\div6=$ $\frac{4}{7}\div\frac{6}{7}=$ $\frac{8}{5}\div12=$
$\frac{1}{2}-\frac{2}{9}=$ $\frac{3}{20}\div\frac{4}{9}=$ $0\div\frac{7}{18}=$ $\frac{1}{4}+2=$
$14\div\frac{35}{4}=$ $\frac{2}{3}\div\frac{2}{7}=$ $\frac{6}{7}\div4=$ $\frac{9}{11}\times44=$

2. 计算下面各题，能简算的要简算。（建议 6 分钟完成）
$\frac{3}{5}\times\frac{3}{4}\times\frac{5}{7}$ $\frac{3}{8}\div\frac{12}{7}\div\frac{3}{4}$ $\frac{1}{14}\div\frac{2}{21}\times\frac{2}{25}$
$\frac{3}{17}\div\frac{9}{34}+\frac{5}{4}$ $(\frac{25}{24}-\frac{3}{8})\div(\frac{4}{9}+\frac{4}{3})$ $(\frac{7}{12}+\frac{3}{4})\div\frac{1}{24}$
