    5.6x0.125用简便方法计算

    5.6x 0.125=0.7*(8x 0.125)=0.7*1=0.7

    正解如下:5.6x0.125=5.6x(1/8)=5.6/8=0.7

    你好!5.6X0.125十2.4÷8=5.6X0.125十2.4X0.125=(5.6+2.4)X0.125=8X0.125=1仅代表个人观点,不喜勿喷,谢谢.

    5.6x12.5=8X12.5X0.7=100X0.7=70

    5.6x0.125=5.6/8*(0.125*8)=0.7*1=0.7

    5.6乘以0.125=0.7*8*0.125=0.7*(8*0.125)=0.7*1=0.7

    =0.7*8*0.125=0.7*1=0.7

    2.5x(3.2x0.125)=2.5*(0.4*8*0.125)=(2.5*0.4)*(8*0.125)=1*1=1

    5.6*2.5/5.6*2.55.6和第二个5.6约掉2.5*2.5=6.25

    64X0.125X0.5X0.125=(64*1/8*1/8)*0.5=1*0.5=0.5
