5.6x 0.125的简便方法

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

你好!5.6x0.125=0.7x8x0.125=0.7x(8x0.125)=0.7x1=0.7仅代表个人观点,不喜勿喷,谢谢.

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.

7.2x0.125=0.9x8x0.125=0.9x(8x0.125)=0.9x1=0.9希望能帮到你!

2.4*0.125=(2+0.4)*0.125=0.25+0.05=0.3

24x0.125=24x1/8=34.89x0.5x2=4.89x1=4.895.6x3.5+4.4x3.5=(5.6+4.4)x3.5=10x3.5=35

6x(1/8) =5.8x0原式 5.6x0.125 =(7x0.8)x0.125 =7x(0.125) =7x0.1 =0.7 或者 =5.6÷8 =0

2.5x0.125X16=2.5X0.125X4X4=(2.5X4)X(0.125X4)=10X0,8=8

0.125x72=0.125x8x9=1x9=9
