1. 直接写出得数。(8 分)
$\frac {5}{12}+\frac {7}{12}=$1 $\frac {2}{3}-\frac {1}{4}=$$\frac{5}{12}$ $\frac {5}{8}×0=$0
$\frac {3}{7}÷\frac {1}{3}=$$\frac{9}{7}$ $6÷\frac {2}{11}=$33 $\frac {4}{9}×\frac {3}{8}=$$\frac{1}{6}$
$\frac {5}{8}+\frac {3}{2}×\frac {1}{3}=$$\frac{9}{8}$ $30-36×\frac {5}{6}=$0

答案： 1. 1 $\frac{5}{12}$ 0 $\frac{9}{7}$ 33 $\frac{1}{6}$ $\frac{9}{8}$ 0

2. 计算下面各题,能简算的要简算。(12 分)
$25-25×\frac {99}{100}$ $\frac {7}{12}+\frac {5}{12}÷\frac {5}{6}+\frac {1}{6}$ $\frac {9}{13}×(13+\frac {1}{9})×9$
$\frac {12}{7}-(\frac {1}{2}×\frac {10}{7}+\frac {4}{5})$ $5×\frac {5}{9}+4÷\frac {9}{5}$ $\frac {5}{7}÷[\frac {3}{5}×(1-\frac {1}{3})]$

答案： 2. $\frac{1}{4}$ $\frac{5}{4}$ $81\frac{9}{13}$ $\frac{1}{5}$ 5 $\frac{25}{14}$

3. 解方程。(9 分)
$\frac {1}{2}x÷\frac {5}{8}= \frac {4}{5}$ $x-\frac {2}{3}x-\frac {1}{3}= 1$ $1-\frac {3}{5}x= \frac {5}{8}$

答案： 3. $x=1$ $x=4$ $x=\frac{5}{8}$

1. (24)米比 20 米长$\frac {1}{5}$;80 千米比(100)千米少$\frac {1}{5}$;45 千克减少$\frac {1}{5}$千克是($44\frac{4}{5}$)千克。

答案： 1. 24 100 $44\frac{4}{5}$
