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

4楼:匿名用户

原式=10÷(1/8×1/4)

=10÷1/32

=10×32

=320

原式=0.125×0.8÷12.5×0.8=0.125÷12.5×0.8×0.8

=0.01×0.8×0.8

=0.0064

7.56÷8÷1.25÷75.6

=75.6/10 × 1/8 × 1/1.25 × 1/75.6

=75.6/10 × 1/(8×1.25) × 1/75.6=1/10 × 1/10
