1. 看谁算的又快又准。
$40\times\frac{3}{8}=$ $1\div\frac{2}{13}=$ $\frac{4}{9}+\frac{8}{27}=$
$\frac{3}{4}+\frac{1}{10}=$ $\frac{9}{5}-\frac{2}{5}=$ $\frac{4}{5}-\frac{7}{25}=$
$\frac{9}{8}\times\frac{4}{3}=$ $\frac{5}{3}\div\frac{3}{4}=$ $\frac{1}{3}\times\frac{9}{7}=$
$\frac{2}{9}\times\frac{5}{6}=$ $\frac{3}{10}\times\frac{4}{9}=$ $\frac{2}{3}+\frac{4}{9}=$
$1-\frac{1}{7}=$ $\frac{7}{8}+\frac{3}{8}=$ $\frac{1}{3}\div\frac{7}{8}=$
$\frac{4}{9}\div\frac{1}{3}=$ $\frac{10}{3}+\frac{6}{5}=$ $\frac{1}{12}\times120=$
$1-\frac{7}{12}=$ $75\times\frac{2}{3}=$ $\frac{5}{8}-\frac{1}{2}=$
$\frac{5}{24}\times\frac{6}{5}=$ $\frac{3}{10}-\frac{1}{4}=$ $\frac{11}{6}\div\frac{6}{7}=$

答案： 15 $\frac{20}{9}$ $\frac{2}{15}$ $\frac{17}{20}$ $\frac{7}{5}$ $\frac{13}{25}$ $\frac{3}{2}$ $\frac{20}{9}$ $\frac{3}{7}$ $\frac{5}{27}$ $\frac{2}{15}$ $\frac{10}{9}$ $\frac{6}{7}$ $\frac{5}{4}$ $\frac{8}{21}$ $\frac{4}{3}$ $\frac{68}{15}$ 10 $\frac{5}{12}$ 50 $\frac{1}{8}$ $\frac{1}{4}$ $\frac{1}{20}$ $\frac{77}{36}$

2. 脱式计算。
$(\frac{3}{4}+\frac{1}{6}+\frac{2}{3})\div\frac{19}{2}$ $\frac{1}{12}\div[(\frac{5}{6}-\frac{1}{2})\times3]$ $(\frac{4}{5}+\frac{1}{4})\div\frac{7}{3}+\frac{3}{10}$
$(\frac{12}{7}-\frac{3}{14}+\frac{3}{4})\div\frac{25}{49}$ $\frac{7}{2}\div\frac{5}{4}+\frac{15}{2}\div\frac{15}{4}$ $[1-(\frac{1}{2}-\frac{1}{3})]\div\frac{5}{8}$

答案： $\frac{1}{2}$ $\frac{1}{9}$ $\frac{3}{4}$ $\frac{32}{5}$ $\frac{21}{20}$ $\frac{29}{48}$
