一、乘法分配律练习

0.3 × 63 ＋ 99.7 × 63 1.2 × 31 ＋ 98.8 × 31

6.1 × 68 ＋ 93.9 × 68 4 4.8 × 61 ＋ 95.2 × 61

4.9 × 45 ＋ 95.1 × 45 4.4 × 20 ＋ 95.6 × 20

1.5 × 24 ＋ 98.5 × 24 7 × 82 ＋ 93 × 82

8.8 × 27 ＋ 91.2 × 27 6.8 × 8 ＋ 93.2 × 8

5.4×9＋8.6×9－4.0×9 9.3×3＋5.9×3－5.2×3

二、乘法结合律练习

25×7.1×4 12.9×25×4 12.5×0.69×8

35×0.2×0.5 0.75×50×0.4 1.28×5.93×80

三、简便计算

25×4.4 8.8×1.25 10.1×5.6

9.9×2.6 1.5×1.6 0.25×3.6

1.6 × 67＋98.4 × 67 0.1×8.2＋0.2×8.2＋9.7× 8.2

25.2÷6= 34.5 ÷1.5= 5.6÷0.04= 1.8÷12=

1.8÷1.2= 7.83÷9= 4.08÷0.8= 0.54÷0.6=

6.3÷0.14= 72÷15= 14.21÷7= 24÷1.5=

1.26÷18= 43.5÷29= 18.9÷0.27= 1.35÷15=

28.6÷11= 20.4÷24= 3.64÷52= 156÷0.12=

328÷1.6= 1.35÷27= 7.65÷0.85= 12.6÷0.28=

62.4÷2.6= 54.4÷0.16= 1.44÷1.8= 11.7÷2.6=

19.4÷12= 59.8÷0.23= 19.76÷5.2= 10.8÷45=

21÷1.4= 8.84÷1.7= 62.1÷0.03= 1.89÷54=

0.51÷2.2= 7.1÷2.5= 1.998÷0.54= 1.28÷16=

2.1÷0.4= 2.56÷32= 50.18÷38.6= 4.68÷75=
