1. 直接写出得数。（建议2分钟完成）
$10\times\frac{3}{5}=$ $6\times\frac{1}{12}=$ $\frac{1}{8}\times24=$ $\frac{5}{36}\div\frac{5}{108}=$
$10+\frac{3}{5}=$ $\frac{3}{10}\div\frac{9}{10}=$ $\frac{1}{3}\times\frac{5}{12}=$ $\frac{3}{8}\div\frac{4}{3}=$
$\frac{1}{2}-\frac{2}{5}=$ $9\div\frac{3}{8}=$ $\frac{4}{5}\times\frac{5}{8}=$ $\frac{16}{45}\div\frac{4}{9}=$
$\frac{33}{25}\times\frac{5}{11}=$ $\frac{3}{10}+\frac{9}{10}=$ $\frac{5}{9}\div10=$ $\frac{5}{32}\times18=$

2. 计算下面各题，能简算的要简算。（建议6分钟完成）
$\frac{15}{13}-\frac{11}{20}-\frac{9}{20}$ $\frac{7}{6}\div\frac{28}{3}\div\frac{9}{8}$ $(\frac{3}{8}+\frac{2}{7})\times8+\frac{5}{7}$
$\frac{11}{15}-(\frac{7}{8}-\frac{4}{15})$ $\frac{7}{12}\div\frac{14}{9}+\frac{5}{12}\times\frac{9}{14}$ $(\frac{4}{5}+\frac{1}{4})\div\frac{7}{5}+\frac{5}{4}$
$(\frac{1}{2}-\frac{1}{3}+\frac{1}{4})\times48$ $5\div(\frac{1}{2}+\frac{1}{6})$ $\frac{3}{25}\div9+\frac{3}{25}\times\frac{8}{9}$

答案： $\frac{2}{13}$@@$\frac{1}{9}$@@6@@$\frac{1}{8}$@@$\frac{9}{14}$@@2@@20@@$\frac{15}{2}$@@$\frac{3}{25}$

用简便方法计算。
$(\frac{3}{4}+\frac{6}{7}+\frac{9}{11})\div(\frac{1}{4}+\frac{2}{7}+\frac{3}{11})$ $(2\frac{4}{5}-2\frac{4}{9})\div(\frac{1}{5}-\frac{1}{9})$

答案： 3@@4
