1.25÷0.58-0.32×0.58＝﹙1.25－0.32﹚×0.58＝0.93×0.58＝﹙1－0.07﹚×0.58＝0.58－0.07×0.58＝0.58－0.0406＝0.5394.

0.87×100.01＝0.87×100＋0.87×0.01＝87＋0.0087＝87.00871.25×0.025×2×0.5×0.32＝﹙1.25×0.8﹚×﹙0.025×0.4﹚×﹙2×0.5﹚

=4x0.25x1.25x0.08=1x0.01=0.01再问：你确定是对的吗

=（12.5×0.8）×（2.5×0.4）=10×1=1088×125=11×（8×125）=11×1000=11000

对的,用的是拆分原理,将0.32分成了0.4和0.8

2.5*1.25*0.32=2.5*1.25*0.4*0.8=2.5*0.4*1.25*0.8=1*1=1

简便2.5×0.32×1.25

2.5×0.32×1.25=（1.25×0.8）×（2.5×0.4）=1×1=1

3.64÷1.25÷0.32=3.64÷(1.25x0.32)=3.64÷(1.25x0.8x0.4)=3.64÷(1x0.4)=3.64÷0.4=9.1

0.5*0.32*1.25*0.025*2=(0.5*2)*0.4*0.8*1.25*0.025=(0.5*2)*(0.8*1.25)*(0.4*0.025)=1*1*0.01=0.01

2.5×1.25×0.32=2.5×1.25×0.4×0.8=(2.5×0.4)×(1.25×0.8)=1×1=1

1.25x2.4=1.25x2+1.25x0.4=2.5+0.5=31.25x0.32x2.5=(1.25x0.8)x(0.4x2.5)=1x1=11.25x2.5x64=1.25x8x(2.5x8)

等着,现在没空,等下给你做好了,给你hi了,做了半天采纳我啊

根据乘法交换律,把0.32拆开来,就有（2.5*0.4）*（0.8*1.25）=1*1=1

1.25*0.32*250=1.25*0.8*0.4*250=1*100=100

9.1再答：小学的？

不对,应该是这样的3.64/(0.4*0.8)/(1.25*0.8/0.8)=3.64/0.4/0.8/(1/0.8)=9.1/0.8/1*0.8=9.1
