1. 看谁算的又快又准。
$\frac{9}{10}-\frac{3}{10}=$ $\frac{7}{8}\times\frac{1}{13}=$ $\frac{5}{8}\times\frac{3}{5}=$
$\frac{1}{3}+\frac{1}{4}=$ $\frac{1}{6}+\frac{3}{5}=$ $\frac{4}{7}-\frac{2}{5}=$
$\frac{1}{4}+\frac{7}{8}=$ $\frac{1}{3}\times\frac{2}{5}=$ $\frac{5}{7}+\frac{10}{21}=$
$\frac{8}{5}\times\frac{5}{12}=$ $\frac{7}{12}+\frac{1}{12}=$ $\frac{11}{12}-\frac{3}{4}=$
$\frac{3}{4}\times\frac{5}{12}=$ $1\div\frac{1}{2}=$ $\frac{1}{3}\times\frac{2}{5}=$
$\frac{3}{8}-\frac{1}{6}=$ $\frac{5}{7}-\frac{2}{7}=$ $\frac{1}{3}+\frac{1}{4}=$
$\frac{1}{3}+\frac{4}{5}=$ $\frac{2}{3}\times\frac{2}{3}=$ $\frac{5}{2}\times\frac{5}{4}=$
$\frac{1}{2}-\frac{1}{4}=$ $\frac{15}{18}-\frac{7}{18}=$ $\frac{5}{6}-\frac{2}{3}=$

答案： $\frac{3}{5}$ $\frac{7}{104}$ $\frac{3}{8}$ $\frac{7}{12}$ $\frac{23}{30}$ $\frac{6}{35}$ $\frac{9}{8}$ $\frac{2}{15}$ $\frac{25}{21}$ $\frac{2}{3}$ $\frac{2}{3}$ $\frac{1}{6}$ $\frac{5}{16}$ 2 $\frac{2}{15}$ $\frac{5}{24}$ $\frac{3}{7}$ $\frac{7}{12}$ $\frac{17}{15}$ $\frac{4}{9}$ $\frac{25}{8}$ $\frac{1}{4}$ $\frac{4}{9}$ $\frac{1}{6}$

2. 脱式计算。
$\frac{1}{8}+\frac{7}{9}-\frac{5}{6}$ $(51+\frac{34}{35})\div17$ $\frac{15}{22}+\frac{6}{11}-\frac{7}{60}$
$\frac{11}{5}\div22+\frac{8}{9}$ $\frac{3}{4}-(\frac{1}{28}+\frac{4}{7})$ $\frac{25}{36}+\frac{15}{4}-\frac{2}{27}$

答案： $\frac{11}{72}$ $3\frac{2}{35}$ $\frac{141}{110}$ $\frac{19}{18}$ 0 $\frac{139}{54}$
