一、口算

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=
二、列竖式计算
7.6×0.35 = 0.756÷0.36 =
三、解方程
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
6.4 3.6×5.2 6.7×101
28×17.5–28×7.5 0.25×32×0.125
14-7.4= 1.92÷0.04=
0.32×500= 0.65+4.35=
10-5.4= 4÷20=
3.5×200= 1.5-0.06=
0.75÷15= 0.4×0.8=
4×0.25= 0.36+1.54= 五年级数学口算
1.01×99= 420÷35=
25×12= 135÷0.5=
0.51÷17= 32.8+19=
5.2÷1.3= 1.6×0.4=
4.9×0.7= 五年级数学口算 1÷5=
6÷12= 0.87-0.49=
