一、直接写出得数

0.5×8=             3.6×0.4=         39.68×0=         47.6×1=   

4÷0.5=             12÷0.06=         12÷1.2=           3÷30= 

0.15×7=            3.2×6+3.2×4=                     2.5×4×0.36=

0.2+0.8×0.5=       6.03×1000=       10×0.6=         6.45×0.01=                  

0.1×0.1=           0.24×0.5=        5.4+3.6=        1.25-0.25=

10.2×4.5=         2.5×6=          9×0.25=        0.125×4=

1.25×8×0.5=      16×0.01=        1.78÷0.3=         0.27÷0.003=

0.01÷0.1=         1.8×20=          x-0.4x=           5d-2d=

3.6÷0.4=           0.6×0.8=       2.4×3=         0.12×0.7=

4÷5=             1.6÷0.5=       0.2÷0.05=       2.5×2.3×4=

1.5÷1.5+1.5=       3.6-1.2÷2.4=          4.7×6+4×4.7=    

0.5×4÷0.5×4=       38.5×0×0.38=          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

 

二、用竖式计算

8.08-2.68=       5.546+29.38=      17.04×0.26 =       8.35×3.5=

三、竖式计算(得数保留一位小数)

0.43×0.29≈             52.6×0.23≈            4.58×0.37≈

  

四、竖式计算(得数保留两位小数)

4.3×8.14≈            27.6×0.45≈            27.6×0.45≈

20÷12≈              2.9×1.8≈              5.08×0.25≈

五、竖式计算(得数保留三位小数)

2.5÷0.7=                 2.5÷0.7=               3.25×9.04=

六、竖式计算(用循环小数表示商)

36.8÷16≈            10.1÷3.3≈        15.3÷11≈          0.78÷1≈

七、脱式计算

(2.65+2.77)÷(1.98-0.98)=          3.7×91.6+6.3×91.6=

0.45×12×0.2=                       6.2×2.1-2.12.8-2.8×0.15=

2.8×1.43+0.57=                    10-6.06+8.5=

6×0.25×1.8=                      144÷3.6+27.2=

 

0.87×3.16+4.64=                  6.8×0.75÷0.5=

13.75÷0.125–2.75=               53+23.4÷7.2=

 

 

2.881÷0.43-0.24×3.5=                  28-(3.4+1.25×2.4)=

 

 

(31.8+3.2×4)÷5=                     31.5×4÷(6+3)=

 

 

0.64×25×7.8+2.2=                   2÷2.5+2.5÷2=

 

 

 

 

194-64.8÷1.8×0.9=                36.72÷4.25×9.9=

 

5180-705×6=                      24÷2.4-2.5×0.8=

 

 

3.416÷(0.016×35)=

 

 

 

 

八、用简便方法计算下面各题

5.12+2.54+4.88=             12.5×17.8×0.8=           9.9×2.5=

 

 

 

 

9.4×5.8+10.6×5.8=        0.125×0.32×0.25=       9.6+9.6×99=

 

 

 

 

2.8×7.6+1.4×2.8 +2.8=       6.3×10.1=           0.25×3.2×12.5=

 

12.5×9.7?12.5×8.7=               3.7×91.6+6.3×91.6=

 

16.84÷40÷0.25=           12.5×0.4×2.5×8=          9.5×101=

4.2×7.8+2.2×4.2=              2.55×7.1+2.45×7.1=
