1. 直接写出得数。(4分)
$7.2+3.8=$11 $201-96=$105 $6÷15\% =$40 $0.25×8=$2
$\frac {2}{5}+\frac {1}{3}=$$\frac{11}{15}$ $\frac {3}{8}×0.4=$$\frac{3}{20}$ $\frac {3}{5}÷\frac {3}{4}=$$\frac{4}{5}$ $\frac {1}{5}×5÷\frac {1}{5}×5=$25

答案： 11 105 40 2 $\frac{11}{15}$ $\frac{3}{20}$ $\frac{4}{5}$ 25

2. 下面各题,怎样简便就怎样算。(18分)
$98+2550÷25×15$ $36÷\frac {3}{4}+36÷\frac {1}{4}$ $25×0.75+23×\frac {3}{4}$
$3.2×25×1.25$ $\frac {4}{7}×37-2÷\frac {7}{4}$ $\frac {3}{8}×[\frac {8}{9}÷(\frac {5}{6}-\frac {3}{4})]$

答案： 1628 192 36 100 20 4

3. 解方程或比例。(6分)
$x:8= 0.25:\frac {1}{4}$ $5x-1.6= \frac {9}{10}$ $\frac {7}{8}+\frac {1}{8}x= 2$

答案： x = 8 x = $\frac{1}{2}$ x = 9
