五年级上册数学计算题（1）

一用竖式、横式计算并验算下面各题。

0.36×12= 4.8×15= 1.02×38= 0.36×23= 0.065×24= 8.4×12= 9.5×15= 2.5×14= 0.32×2.05= 7.05×0.24= 1.95×8.6= 0.67×0.23= 2.58×2.4= 1.44×2.8= 1.3×2.5= 24.5×0.9=

1.08×0.29= 9.5×4.07= 5.08×

2.5= 2.8×0.06= 0.09×1.87= 9.6×0.52= 4.32÷16= 1.53÷34= 12.96÷32= 37.8÷18= 5.1÷15= 2.4÷0.28= 40÷125= 50.4÷0.28= 0.7÷0.035= 5.76÷1.8=

11.5÷4.6= 0.45÷1.8= 0.15÷1.2= 16.2÷0.45= 7.05÷0.94= 14÷0.56= 63÷1.4=

21÷2.2= 225.82÷14= 2.61÷1.8= 0.25×0.12= 2.4×1.35= 3.06×25= 4.7×0.53= 36.5×0.04=

5.32×0.36= 0.12×30.8= 1 6.75×5.4＝62.5÷25＝

二、先用竖式再把得数保留一位小数 7.5×4.3 ≈7.85×6.3≈0.4×1.7≈ 2.07× 3.8≈ 1.25× 4.2≈

≈17.9÷2.9≈57.8÷2.04≈

三、先竖式再把得数保留两位小数 1.78×0.24≈0.56×1.07≈0.019×5.7 3.15÷4.7≈32÷3

2.3≈40.91÷51≈185÷32≈ 5.586÷0.72≈1.57÷

≈37.2÷42

≈

1.9×0.26≈2.7×6.08≈10.05÷32≈

4.035÷2.4≈9.87÷2.3≈87.5÷3.7≈46.9÷8.7≈38.1÷6.9

0.672÷4.2=

0.24÷4.8=

12.6÷3.5=

24÷0.96=

2.496÷0.12= 39.68÷0.32= 170.3÷2.6= 255.5÷3.5= 19.44÷2.7=

3.9≈0.13÷0.17≈ 3.27÷8.5≈ 3.69÷1.7≈62÷29≈40.8÷27≈ 四、先竖式再在横式上用循环小数表示

3÷1.1= 3.38÷1.8= 13.32÷15= 3÷40= 5÷7= 14.2÷11= 3.82÷2.7= 5.7÷11=
