0.35x1.25x2x0.8简便计算

0.35x1.25x2x0.8 =(0.35x2)x(1.25x0.8) =07x1 =0.7

解: 0.35x1.25x8x2 原式=(0.35x2)x(1.25x8) =0.7x10 =7.望采纳,你的采纳是我前行的动力!

先算1.25*0.8得1,再用0.35*2得0.7,用0.7*1得0.7 再看看别人怎么说的.

1.25*0.8=1

=12.5*0.8*0.96=10*0.96=9.6

1.25x0.35x0.48=1.25x0.5x0.7x0.8x0.6=(1.25x0.8)x(0.5x0.6)x0.7=1x0.3x0.7=0.21谢谢,请采纳

(0.35*2)

1.25x0.24x0.8=5x0.25x0.4x0.6x0.8=(5x0.6x0.8)x(0.25x0.4)=(3x0.8)x0.1=2.4x0.1=0.24若满意,请采纳,您的采纳是我回答问题的动力哦!

=(0.35*2)*(1.25*08)=0.7*1=0.7

1.25*0.36*0.8=1.25*0.8*0.36 (乘法交换律)=1*0.36=0.36
