2.4x0.25的简算

2.4X0.25=4x0.6x0.25=4x0.25x0.6=1x0.6=0.6 祝你学习进步,有不明白的可以追问!谢谢!!

2.4x45x0.25=0.6*4*45*0.25=0.6*45*4*0.25=27*1=27

=7.6x0.25+2.4x0.25=(7.6+2.4)x0.25=1x0.25=0.25

展开全部2.4*1.25=2.4*5/4=0.6*5=3

2.4*0.25=0.6.简便计算过程如下:2.4*0.25=0.6*4*0.25=0.6*1=0.6或者2.4*0.25=(2.4÷0.4)*(0.25*4)=2.4÷0.4*1=2.4÷0.4=0.6扩展资料:乘法:1)乘法交换律:a*b=b*a2)乘法结合律:a*b*c=(a*b)*c=a*(b*c)3)乘法分配律:(a+b)*c=a*c+b*c;(a-b)*

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

2.4*1.25=(0.6*4)*(0.25*5)=(0.6*5)*(0.25*4)=3*1=3

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

=(10-0.4)*0.25=10*0.25-0.4*0.25=2.5-0.1=2.4

2.4x2.5+17x0.25-0.25=24 x0.25+17 x0.25-0.25=0.25 x (24+17-1)=0.25 x40=10 1.4x0.8*(6.32+4.88)=1.4 x0.8 x11.2=1.12 x11.2=12.544 已解决,望采纳.谢谢.
