0.25 0.5 2.4简便计算

0.25*0.5*2.4=0.25*0.5*4*0.6=(0.25*4)*(0.5*0.6)=1*0.3=0.3

0.25乘0.5乘2.4=0.25x8x0.3x0.5=1x0.15=0.15

0.25*2.4 =0.25*4*0.6 =1*0.6 =0.6

0.25X2.4=0.25X4X0.6=1X0.6=0.6

2.4*0.5*0.4*5=(5*0.4)*0.5*2.4=(2*0.5)*2.4=1*2.4=2.4很高兴为您解答,祝你学习进步!有不明白的可以追问!如果您认可我的回答,请点击下面的【选为满意回答】按钮,谢谢!

简便计算0.25Ⅹ2.4÷0.5X2.4=(0.25÷0.5)x(2.4x2.4)=0.5x5.76=2.88

=(2+0.4)*0.25=2*0.25+0.4*0.25=0.5+0.1=0.6 乘法分配律

2.4*0.25 =(2+0.4)*0.25 =2*0.25+0.4*0.25 =0.5+0.1 =0.6

0.25*0.5*2.4=0.25*0.5*4*0.6=(0.25*4)*(0.5*0.6)=1*0.3=0.3

(2.4 X 4) / (0.25 X 4)=2.4 X 4=9.6
