一、口算（每题1分,共12分）.
0.6×2.5= 7×0.03= 12.5÷2.5= 2.8×0.3=
4.5÷0.01= 1.8×50= 64÷1.6= 0.48×0.2=
5.4÷0.27= 10－0.13= 92= 53＝
二、列竖式计算（每题4分,共8分）.
7.6×0.35 =
0.756÷0.36 =
三、解方程（每题6分,共24分）.
2 x – 9.1 =4.7 2.7+4x = 12.7

6 (x + 1.2) = 24 4.2 x + 2.5 x = 134
四、计算下面各题,能简算的要简算（每题5分,共20分）.
6.4+ 3.6×5.2 6.7×101

28×17.5–28×7.5 0.25×32×0.125
五、把下列的假分数化成带分数或整数（每题3分,共18分）.
275 = 186 = 194 =
158 = 213 = 209 =
六、把下列带分数化成假分数（每题3分,共18分）.
138 = 856 = 212 =
314 = 1013 = 515 = 一、口算（每题1分,共12分）.
