0.25*32*0.125怎么简便

0.125*32*0.25=0.125*8*4*0.25=1*4*0.25=1

0.125*0.25*32=0.125*8*0.25*4=1*1=1

=0.125*8*4*0.25=1*1=1

32分为4乘8.然后,4乘0.25,8乘0.125

你好,很高兴为你解答!原式=1/8*32*1/4 =4*1/4 =1希望能够帮助到你,谢谢!

32 x 0.25 x 0.125 = (4 x 8 )x 0.25 x 0.125(将32拆分成4 x 8 ) = 4 x 0.25 x 8 x 0.125(乘法就交换律) = (4 x 0.25) x (8 x 0.125)(乘法结合律) = 1 x 1 = 1 技巧:当看到0.25和0.125,就想到4 x 0.25 = 1 和 8 x 0.125 = 1 这样的公式.所以把32拆成

简便运算2.5*0.32*0.125=(2.5*0.4)*(0.8*0.125)=1*0.1=0.1

0.125*0.25*32=0.125*0.25*(4*8)=0.125*8+0.25*4=1+1=2

0.25*0.125=0.125/4=0.03125

0.125*32*0.25=0.125*(8*4)*0.25=(0.125*8)*(4*0.25)=1
