1、直接写出得数。

0.45×2.5=0.8×1.25=0.3×3.6=0.3×0.3=10×0.07=0.3×1.4=0.05×7=0.92×0.4=0.2×0.26=0.14×4=0.02×0.1= 1.2×0.3=0.2×0.4=8.2+1.8=100-35.22=2.3×4= 2.5×0.4= 2.4×5=0.22×4= 3.25×0=

0.9-0.52= 3.99×1=0×3.52=12.5×8=1÷0.5=

8÷10 = 10-1.8-7.2= 0.43+3.57= 2.5×4×12= 1.05×100=

0.9×0.8= 0.96÷3= 1.47÷0.7= 5.4÷6= 4÷0.8 =

0.16.5×10= 0.56×100= 3.78×100= 3.215×100= 0.8×10= 4.08×100= 1.1×0.2 = 0.6×0.8 = 3×0.9= 2.5×0.4= 3.6×0.4= 12.5×8= 50×0.04= 80×0.3 = 1.1×9=

0.16×5 = 1.78+2.2 = 9.6÷0.6 = 1.2×0.5-0.4 = 0.7÷0.01 = 2.5×0.4 = 12-3.9= 1.25×8÷1.25 = 6.6÷0.66 = 5.37×0+4.63 = 4.2÷3.5= 1.6+2.4×0.3 = 2.14-0.9=27+456+73= 0.3×0.3= 7.2+2.8=0.9÷0.01=12÷0.3= 2.87÷0.7=13÷4=0.96÷0.3= 1.5×0.4=7÷0.25= 2.5×0.7×0.8= 8-2.5=16÷1.6= 5.6×1.01= 8×(2.5+0.25)=0.36+0.64=64.32÷16=72.8÷0.8=8.4÷4.2=13.8+9.9= 2.4×2.5=0.05×0.8=1.25×0.8×0.5=12×2.5= 1.23×3= 3.2÷1.6= 3.5+3.5×3=19.6÷2=8.8÷2.2= 0.75×4=(1.5+0.25)×4=0.5×0.8=

8.4×0.2= 1.6×0.2=7.2×0.3= 2.8×0.3=0.9÷0.15= 1.8×0.4= 5.5÷0.55= 0.08×100= 2.2÷0.11= 5.46+4.54= 12.5×0.8= 0.35×0.3= 1.4×5= 2.8×4= 19.6÷4= 22.5×4=

2、用竖式计算

0.396÷1.2= 0.756÷0.36= 15.6×13=

0.18×15= 0.025×14= 3.06×36=

0.04×0.12= 3.84×2.6≈ 5.76×3=

(保留一位小数)

7.15×22 90.75÷3.3 3.68×0.2

16.9÷0.13 1.55÷3.9 3.7×0.016

13.76×0.8= 5.2×0.6 8.4×1.3

6.4×0.5 4.48×0.4 5.25×5

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= 4.8×0.25=0.125×1.4(保留两位小数)2.5÷0.7= (保留三位小数)10.1÷3.3= (商用循环小数)10.75÷12.5= (用乘法验算) 3.25×9.04= (用除法验算)

3、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 3.94+34.3×0.2

26×15.7+15.7×24 (2.275 +0.625)×0.28 1.2×(9.6÷2.4)÷4.8 8.9×1.1×4.7 2.7×5.4×3.9 3.6×9.85-5.46

8.05×3.4+7.6 6.58×4.5×0.9 2.8×0.5+1.58 32+4.9-0.9 4.8-4.8×0.5 (1.25-0.125)×8 4.8×100.1 56.5×99+56.5 7.09×10.8-0.8×7.09

4.85 + 0.35 ÷ 1.4 8.7 × 17.4 - 8.7 × 7.4 2.13.×0.×8257

12.5×0.4×2.5×8 0.87×3.16+4.64 9.5×101

0.68 ÷(5.2 -3.5)× 1.25 4.8 ×(15 ÷ 2.4)40.5 ÷ 0.81 × 0.18

6.81+6.81×99 0.25×185×40 4 .4×0.8-3.4×0.8 0.25×39+0.25

(9.37+9.37+9.37+9.37)× 2.5 4.2.×1.+1.×1.75 46×0.33+54×0.3 2.37×6.3+2.37×3.7 2.5×1.25×0.32 3.8×10.1 0.125×72 2.5×(3.8×0.04) 7.69×101 3.8×10.1
