小数计算题

1、用竖式计算
0.396÷1.2= 0.756÷0.36= 15.6×13=
0.18×15= 0.025×14= 06×36=
0.04×0.12= 3.84×2.6≈(保留一位小数) 5.76×23=
7.15×22= 90.75÷3.3= 3.68×0.25=
16.9÷0.13 = 1.55÷3.9= 3.7×0.016=
13.76×0.8= 5.2×0.6 8.4×1.3 =
6.4×2.5= 4.48×4.4= 5.25×15 =
35.4×4.2= 0.042×0.54 = 0.76×0.32 =
0.25×0.046= 2.52×3.4= 1.08×25=
0.12×0.5×0.16= (保留两位小数) 3.25×9.04= (用除法验算)
4.8×0.25= 0.125×1.4≈ 10.75÷12.5= (用乘法验算)
2.5÷0.7= (保留三位小数) 10.1÷3.3= (商用回圈小数表示)
0.43×0.28= 6.45×0.73= 4.6×0.6=
8.9×0.05= 3.08×0.43= 1.5×26.7=
5.22÷29= 18.72÷3.6= 13.95÷3.1=
2、脱式计算(能简算的要简算)
2.5×7.1×4 = 16.12×99+16.12= 5.2×0.9+0.9= 7.28×99+7.28=

4.3×50×0.2= 64-2.64×0.5=2 6×15.7+15.7×24= (2.275 +0.625)×0.28=

3.94+34.3×0.2= 1.2×(9.6÷2.4)÷4.8= 8.9×1.1×4.7= 2.7×5.4×3.9=

3.6×9.85-5.6 = 8.05×3.4+7.6 = 6.58×4.5×0.9= 2.8×0.5+1.58=

4.85 + 0.35 ÷ 1.4= 8.7 × 17.4 - 8.7 × 7.4= (1.25-0.125)×8=

32+4.9-0.9= 4.8-4.8×0.5 =

4.8×100.1 = 56.5×99+56.5 = 7.09×10.8-0.8×7.09=
12.5×0.4×2.5×8 = 0.87×3.16+4.64 = 9.5×101=
0.68 ÷(5.2 -3.5)× 1.25= 2.13.×0.×8257=

40.5 ÷ 0.81 × 0.18= 4.8 ×(15 ÷ 2.4)=
6.81+6.81×99= 0.25×185×40= 4.4×0.8-3.4×0.8=

(9.37+9.37+9.37+9.37)× 2.5= 4.2.×1.+1.×1.75=
2.37×6.3+2.37×3.7= 2.5×1.25×0.32= 3.8×10.1=
2.5×(3.8×0.04=) 7.69×101 = 3.8×10.1 =

0.25×39+0.25= 0.125×72 = 46×0.33+54×0.33=

(8×5.27) ×1.25 = 6.81+6.81×99 = 0.25×185×40=

6.8×0.75÷0.5 = 3.75÷0.125–2.75= 1.53+23.4÷7.2=
9.5×99= 13.5×0.98= 12.5×8.8 =

2.6-0.8*5.2
=2.6-0.8*2.6*2
=2.6(1-1.6)
=2.6*(-0.6)
=-1.56
