4.44 0.75简便

简便算法就是将4.44看成4+0.4+0.04,所以原式可以化简为4*0.75+0.4*0.75+0.04*0.75=3.33

简便计算4.44*0.75=1.11x4x3x0.25=(1.11x3)x(4x0.25)=3.33x1=3.33

解:4.44x0.25+0.75 =4.44x1/4+0.75 =1.11+0.75 =1.86

4.440.75=4.44(3/4)=1.113=3.33

4.44*0.75巧算怎么解?4.44*0.75=1.11*(4*0.75)=1.11*3=3.33

4.44*0.25+0.75=4*0.25*1.11+0.75=1.11+0.75=1.86

444x025+075=(4+0.4+0.04)*0.25+0.75=1+0.1+0.01+0.75=1.86

答:4.44/0.25+0.75=17.76+0.75=18.51

=(4.56十4.44)X1.5=9X1.5=13.5

39*0.75的计算可以先把小数0.75化成分数3/4,再用乘法分配律算. 39*0.75=39x(3/4)=(40-1)x(3/4)=40x(3/4)-1x(3/4)=30-3/4=30-0.75=29.25.
