$\frac {2}{15}÷\frac {1}{3}=$$\frac{2}{5}$ $\frac {3}{4}÷\frac {3}{4}=$1 $\frac {2}{3}÷\frac {1}{3}=$2 $\frac {1}{10}÷\frac {8}{21}=$$\frac{21}{80}$
$\frac {5}{8}÷\frac {3}{8}=$$\frac{5}{3}$ $\frac {3}{5}÷\frac {9}{10}=$$\frac{2}{3}$ $\frac {7}{11}÷\frac {7}{9}=$$\frac{9}{11}$ $\frac {2}{21}÷\frac {6}{7}=$$\frac{1}{9}$
$\frac {8}{15}÷\frac {2}{5}=$$\frac{4}{3}$ $\frac {7}{26}÷\frac {21}{13}=$$\frac{1}{6}$ $\frac {5}{33}÷\frac {5}{22}=$$\frac{2}{3}$ $\frac {3}{5}÷\frac {7}{12}=$$\frac{36}{35}$
$\frac {1}{5}÷\frac {7}{10}=$$\frac{2}{7}$ $\frac {5}{8}÷\frac {1}{6}=$$\frac{15}{4}$ $\frac {1}{5}÷\frac {4}{3}=$$\frac{3}{20}$ $\frac {7}{9}÷\frac {7}{18}=$2

答案： $\frac{2}{3}$ $\frac{15}{8}$ $\frac{5}{18}$ 28
$\frac{2}{5}$ 1 2 $\frac{21}{80}$
$\frac{5}{3}$ $\frac{2}{3}$ $\frac{9}{11}$ $\frac{1}{9}$
$\frac{4}{3}$ $\frac{1}{6}$ $\frac{2}{3}$ $\frac{36}{35}$
$\frac{2}{7}$ $\frac{15}{4}$ $\frac{3}{20}$ 2

2. 计算下面各题。(写出计算过程)(每题 3★)
$\frac {16}{25}÷\frac {8}{15}$ $\frac {1}{5}÷\frac {15}{28}$ $\frac {7}{81}÷\frac {5}{12}$

答案： $\frac{6}{5}$ $\frac{28}{75}$ $\frac{28}{135}$
（计算过程略）

3. 解方程。(每题 3★)
$\frac {4}{5}x= \frac {16}{35}$，$x=$$\frac{4}{7}$ $\frac {4}{7}x= 10$，$x=$$\frac{35}{2}$ $\frac {7}{11}x= 42$，$x=$66
$\frac {1}{4}x= 23$，$x=$92 $\frac {4}{5}x= \frac {8}{15}$，$x=$$\frac{2}{3}$ $\frac {8}{15}x= \frac {2}{5}$，$x=$$\frac{3}{4}$

答案： $x=\frac{4}{7}$ $x=\frac{35}{2}$ $x=66$
$x=92$ $x=\frac{2}{3}$ $x=\frac{3}{4}$
