0.15乘以0.2除以0.5的脱式计算怎么算

0.15乘以0.2除以0.5的脱式计算怎么算 =0.15x0.2/(1/2) =0.15x2x0.2 =0.3x0.2 =0.06

列式计算为 0.5÷2.2=0.23 所以原式的结果保留两位小数是0.23

105*0/5 =0/5 =0 0与任何相乘都得0 0除以任何数都得0。

方便计算 2.1÷(0.6x0.5) =2.1÷0.3 =7

5.1÷(0.5+1.2)=5.1÷1.7=3

2.1×0.5÷4.2的脱式计算 =(2.1/4.2)×0.5 =1/2×0.5 =1/2×1/2 =1/4

-100乘以25分之一除以25乘以0.5--10 =-4×1/25×1/2-10 =-2/25-10 =-10又2/25

解:1.8/0.5 =(1.8*2)/(0.5*2) =3.6/1 =3.6

0.78除以26加零点五乘以零点零二 =0.03+0.01 =0.04

脱式计算 12÷1.5+0.5÷15×1.6 =8+1/30×1.6 =8+4/75 =8又4/75
