$\frac {4}{9}÷2=$$\frac{2}{9}$ $\frac {3}{7}÷3=$$\frac{1}{7}$ $\frac {7}{12}÷7=$$\frac{1}{12}$ $\frac {6}{7}÷2=$$\frac{3}{7}$
$\frac {4}{15}÷4=$$\frac{1}{15}$ $\frac {2}{3}÷6=$$\frac{1}{9}$ $\frac {65}{67}÷13=$$\frac{5}{67}$ $\frac {9}{10}÷3=$$\frac{3}{10}$
$\frac {2}{3}÷3=$$\frac{2}{9}$ $\frac {1}{8}÷8=$$\frac{1}{64}$ $\frac {1}{5}÷3=$$\frac{1}{15}$ $\frac {10}{11}÷5=$$\frac{2}{11}$
$\frac {8}{15}÷4=$$\frac{2}{15}$ $\frac {6}{11}÷3=$$\frac{2}{11}$ $\frac {4}{15}÷8=$$\frac{1}{30}$ $\frac {15}{16}÷5=$$\frac{3}{16}$
$\frac {5}{13}÷3=$$\frac{5}{39}$ $\frac {1}{2}÷5=$$\frac{1}{10}$ $\frac {4}{5}÷2=$$\frac{2}{5}$ $\frac {1}{4}÷4=$$\frac{1}{16}$

答案： $\frac{2}{9}$ $\frac{1}{7}$ $\frac{1}{12}$ $\frac{3}{7}$
$\frac{1}{15}$ $\frac{1}{9}$ $\frac{5}{67}$ $\frac{3}{10}$
$\frac{2}{9}$ $\frac{1}{64}$ $\frac{1}{15}$ $\frac{2}{11}$
$\frac{2}{15}$ $\frac{2}{11}$ $\frac{1}{30}$ $\frac{3}{16}$
$\frac{5}{39}$ $\frac{1}{10}$ $\frac{2}{5}$ $\frac{1}{16}$

2. 计算下面各题,能简算的要简算。(每题 3★)
$8-\frac {9}{16}-\frac {7}{16}$ $3.56×4+64.4×0.4$ $\frac {9}{16}-(\frac {1}{2}-\frac {7}{16})$
$0.125×32×25$ $1\frac {8}{9}-\frac {2}{3}+\frac {1}{3}$ $3.5-(\frac {9}{10}-\frac {3}{20})$

答案： 7 40 $\frac{1}{2}$
100 $\frac{14}{9}$ $\frac{11}{4}$

3. 解方程。(每题 3★)
$6x= \frac {3}{20}$，解得$x=$$\frac{1}{40}$
$7x-10= 7.5$，解得$x=$$2.5$
$12x= \frac {8}{5}$，解得$x=$$\frac{2}{15}$

答案： $x=\frac{1}{40}$ $x=2.5$ $x=\frac{2}{15}$
