#### 一、直接写出得数。（每题1分，共32分）
$9\div\frac{5}{6}=$ $\frac{3}{10}\div2=$ $\frac{3}{5}\div\frac{1}{4}=$ $\frac{1}{2}+\frac{3}{4}-\frac{7}{8}=$
$\frac{8}{5}\div\frac{8}{35}=$ $\frac{12}{13}\div\frac{2}{13}=$ $\frac{18}{5}\div\frac{4}{9}=$ $\frac{5}{9}-\frac{1}{3}+\frac{17}{27}=$
$\frac{25}{9}\div5=$ $\frac{5}{9}\times5=$ $\frac{8}{9}\div\frac{5}{18}=$ $\frac{5}{9}-\frac{1}{3}+\frac{7}{9}=$
$\frac{4}{9}\div\frac{9}{4}=$ $\frac{12}{35}\div\frac{12}{7}=$ $\frac{14}{15}\div\frac{28}{3}=$ $\frac{2}{3}-\frac{1}{14}+\frac{1}{3}=$
$\frac{1}{5}\div3=$ $16\div\frac{4}{7}=$ $\frac{3}{10}\div\frac{3}{40}=$ $\frac{4}{9}+\frac{2}{27}+\frac{5}{27}=$
$\frac{2}{13}\times6=$ $\frac{5}{12}\div\frac{25}{36}=$ $\frac{49}{72}\times\frac{9}{14}=$ $\frac{1}{4}+\frac{1}{7}+\frac{1}{2}=$
$0\div\frac{4}{19}=$ $\frac{1}{7}+\frac{3}{4}=$ $\frac{9}{14}-\frac{3}{7}=$ $\frac{3}{5}-\frac{1}{2}+\frac{3}{4}=$
$\frac{5}{6}\times\frac{3}{5}=$ $\frac{10}{21}\div\frac{40}{21}=$ $8\div\frac{4}{7}=$ $\frac{4}{7}+\frac{1}{3}+\frac{1}{2}=$

答案： $\frac{54}{5}$ $\frac{3}{20}$ $\frac{12}{5}$ $\frac{3}{8}$
7 6 $\frac{81}{10}$ $\frac{23}{27}$
$\frac{5}{9}$ $\frac{25}{9}$ $\frac{16}{5}$ 1
$\frac{16}{81}$ $\frac{1}{5}$ $\frac{1}{10}$ $\frac{13}{14}$
$\frac{1}{15}$ 28 4 $\frac{19}{27}$
$\frac{12}{13}$ $\frac{3}{5}$ $\frac{7}{16}$ $\frac{25}{28}$
0 $\frac{25}{28}$ $\frac{3}{14}$ $\frac{17}{20}$
$\frac{1}{2}$ $\frac{1}{4}$ 14 $\frac{59}{42}$

#### 二、解方程。（每题3分，共27分）
$\frac{5}{6}+\frac{3}{4}x=\frac{6}{5}$ $\frac{1}{5}-\frac{3}{25}+x=\frac{3}{5}$ $x-\frac{1}{4}=\frac{3}{4}-\frac{1}{2}$
$3x + 3.6 - 4.5 = 11.1$ $\frac{8}{9}x=\frac{1}{6}\times\frac{16}{51}$ $\frac{1}{3}+\frac{2}{5}-x=\frac{1}{6}$
$(x - 3.06)\div0.3 = 13.8$ $\frac{4}{5}x-\frac{2}{5}=\frac{9}{10}$ $6x = 42\times\frac{1}{6}$

答案： $x = \frac{22}{45}$ $x = \frac{13}{25}$ $x = \frac{1}{2}$
$x = 4$ $x = \frac{1}{17}$ $x = \frac{17}{30}$
$x = 7.2$ $x = \frac{13}{8}$ $x = \frac{7}{6}$
