五年级上册数学计算专项练习题

一、口算

0.9÷0.01=7÷0.25=8.5×0.1=20÷0.5=9×0.2＋0.8=

1＋0.45=7×0.9=1.2÷3=2.4×0.6=20－6.8=

0.84÷0.2=3.5＋3.3×3=0.4＋1.5=8.6－7=0.4×0.9=

2.5×4=3.9÷3.9=2.4÷0.08=0.25×4×6=9.6÷0.3=

2.3＋4.7=0.5×1.1=0×12.5=5.6÷0.8=3.5×0.2=

0÷5.55=0.36÷0.09=4.3－2.3=23.7÷10=1×9.9=

2.8÷0.4=0.213×0.05=9.8÷0.7=1.8－0.5=3.2÷32=

1.5－0.06=6.2－0.5=0.48÷12=3÷0.5=3.2－2.6=

3.2－2.9=21÷0.3=213×5=21.3×5=2.13×0.5=

5a－a=1.2×0.4＋1.3×0.4=0.1×0.1=5.4＋7=0.6×0.9=

0.78×100=1.85×0=5×0.4＋5×1.6=0.39÷0.03=

0.37×10=0.37×100=0.37×1000=25×4=2.5×4=

0.25×4=2.8＋8=5×12=5×1.2=5×0.12=

13×3=1.3×30=0.13×300=8×0.5=2.4÷4=

4.5÷5=12.5＋0.5=16×0.5=1.2÷3=0.3×0.7=

7.2÷0.8=24.8－8=3.2÷4=0.23×3=4.8÷6=

5.6÷7=0.25×4=1.3×0.2=2÷0.5=0.24÷0.2=

0.4÷8=6÷0.02=4.68÷0.02=1÷0.25=1÷8=

二、列竖式计算：

0.5×18=2.48×60=1.05×0.02=

1.08×6.3=12.5×8=6.24÷0.3=

18÷12=1.09÷12=28.6÷11=

1.17÷9=1÷8=81.9÷39=

6.21÷3=0.28×34=0.3×0.75=

2.15×6.8=0.468÷12=2.85×5.2=

18.9÷2.3≈2.5÷24≈700÷12≈

18÷21≈45.86÷2.2≈3.74÷1.3≈

25.5÷0.65≈19.8÷12=93÷0.31=86.4÷32=

三、脱式计算（能用简便方法的用简便方法计算）

4.2×7.8＋2.2×4.20.9＋0.9×998.45－0.45×0.1

19.4×0.9＋0.1×19.42.3＋9×（22－19.7）

6.8×99＋6.82.06＋2.06×991.9×2.34＋1.9×7.66

4.2×7.8＋2.2×4.2
