1. 直接写出得数。(8分)
$\frac {4}{9}×\frac {3}{8}=$$\frac{1}{6}$ $\frac {8}{3}÷\frac {1}{6}=$16 $1÷\frac {5}{8}=$$\frac{8}{5}$
$5÷25\% =$20 $0.5^{2}=$0.25 $5-5×\frac {1}{5}=$4
$24×\frac {1}{2}×\frac {1}{8}=$$\frac{3}{2}$ $4×(\frac {1}{4}-\frac {1}{5})=$$\frac{1}{5}$

答案： $\frac{1}{6}$ 16 $\frac{8}{5}$ 20 0.25 4 $\frac{3}{2}$ $\frac{1}{5}$

2. 下面各题,怎样算简便就怎样算。(18分)
$\frac {16}{17}÷\frac {3}{2}+\frac {1}{3}×\frac {16}{17}$ $36×(\frac {5}{6}-\frac {2}{9}+\frac {3}{4})$
$\frac {5}{8}÷[\frac {7}{5}-(\frac {2}{5}+\frac {3}{8})]$ $[1-(\frac {1}{4}+\frac {3}{8})]÷\frac {1}{4}$
$796+802+803+799+805$ $0.74+0.76+0.738+0.749$

答案： $\frac{16}{17}$ 49 1 $\frac{3}{2}$ 4005 2.987

3. 解方程。(9分)
$x+15\% x= 115$ $\frac {3}{7}x-\frac {1}{8}= \frac {5}{2}$ $\frac {5}{9}x÷2= \frac {1}{2}$

答案： $x=100$ $x=\frac{49}{8}$ $x=\frac{9}{5}$
