1、.小学五年级数学上册计算题一、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=          0.2

2、4×0.5=       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

3、÷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=    3.6×0.412.5×8=    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＝  页脚.三、竖式计算（得数保留一位小数）0.43×0.29≈      

4、      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≈ 

5、        0.78÷1≈ 页脚. 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= 

6、             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)=页脚. 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、

7、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= 页脚.12.5×9.7?12.5×8.7=              3.7×91
