10÷(0.125×0.25)= 0.125×0.8÷12.5×0.8= 问一下这两道题有简算么
2楼:匿名用户
把小数化成分数会简单一点
0.125=1/18;0.25=1/4
10÷(0.125×0.25)
=10÷( 1/8 x 1/4 )
=10÷ 1/32
=10x32
=320
0.125×0.8÷12.5×0.8
= 1/8 x0.8÷ 100/8 x 0.8= 0.1 x 8/100 x 0.8
=0.0064
(乘除混合运算应该是按顺序从左往右算哦。。。?)

第一个可根据除法商不变的性质简算
10÷(0.125×0.25)
=(10×32)÷(0.125×8×0.25×4)=320÷1=32
