$\frac {5}{12}÷\frac {1}{12}=$5 $\frac {3}{20}÷\frac {1}{7}=$$\frac{21}{20}$ $\frac {5}{7}÷\frac {1}{4}=$$\frac{20}{7}$ $\frac {1}{3}÷\frac {1}{9}=$3
$0÷\frac {1}{100}=$0 $\frac {3}{7}÷\frac {1}{3}=$$\frac{9}{7}$ $\frac {21}{40}÷\frac {7}{8}=$$\frac{3}{5}$ $\frac {13}{25}÷13=$$\frac{1}{25}$
$13÷\frac {2}{7}=$$\frac{91}{2}$ $\frac {15}{16}÷5=$$\frac{3}{16}$ $\frac {1}{8}÷\frac {5}{2}=$$\frac{1}{20}$ $\frac {3}{8}÷\frac {6}{7}=$$\frac{7}{16}$
$4÷\frac {8}{3}=$$\frac{3}{2}$ $\frac {1}{6}÷\frac {1}{7}=$$\frac{7}{6}$ $15÷\frac {5}{4}=$12 $\frac {13}{34}÷\frac {13}{34}=$1
$\frac {6}{5}÷\frac {6}{15}=$3 $\frac {3}{8}÷\frac {3}{4}=$$\frac{1}{2}$ $\frac {4}{15}÷\frac {8}{9}=$$\frac{3}{10}$ $8÷\frac {4}{5}=$10

答案： 5 $\frac{21}{20}$ $\frac{20}{7}$ 3
0 $\frac{9}{7}$ $\frac{3}{5}$ $\frac{1}{25}$
$\frac{91}{2}$ $\frac{3}{16}$ $\frac{1}{20}$ $\frac{7}{16}$
$\frac{3}{2}$ $\frac{7}{6}$ 12 1
3 $\frac{1}{2}$ $\frac{3}{10}$ 10

2. 解方程。(每题 3★)
$5x= \frac {10}{9}$，$x=$$\frac{2}{9}$ $\frac {4}{5}x= \frac {8}{35}$，$x=$$\frac{2}{7}$ $\frac {4}{7}x= 20$，$x=$35
$\frac {5}{7}x= 35$，$x=$49 $\frac {7}{9}x= \frac {49}{72}$，$x=$$\frac{7}{8}$ $\frac {4}{15}x= \frac {2}{5}$，$x=$$\frac{3}{2}$
$4x= \frac {8}{13}$，$x=$$\frac{2}{13}$ $\frac {3}{8}x= 15$，$x=$40 $\frac {2}{3}x= \frac {4}{5}$，$x=$$\frac{6}{5}$

答案： $x=\frac{2}{9}$ $x=\frac{2}{7}$ $x=35$
$x=49$ $x=\frac{7}{8}$ $x=\frac{3}{2}$
$x=\frac{2}{13}$ $x=40$ $x=\frac{6}{5}$
