简便运算五年级下册2.5 0.125\/8
2.5÷ 0.125\/8 =2.5÷ (1\/8)\/8 =2.5÷1\/64 =2.5x64 =2.5x4x16 =10x16 =160 谢谢,请采纳
2.5÷0.125÷8简便算式?
=2.5÷(0.125×8)=2.5÷1 =2.5
(2.5 0.125)╳8道简便算法是什么
(2.5+ 0.125)╳8 =2.5*8+0.125*8 =20+1 =21 满意采纳
二点吧五除以0.125除以零点八的简便运算
=2.85÷(0.125×0.8)=2.85÷0.1 =28.5 因为我们知道125×8=1000,所以看到125和8这几个数字,果断把他们放在一起运算,所以 这一题0.125×0.8就是1000的小数点往前进4位=0.1,再进行运算就简单了,简便运算应该就是酱紫滴, \\(^o^)\/ ...
0.532\/0.125\/8的简便方法
简便方法 0.532÷0.125÷8 =0.532÷(0.125×8)=0.532÷1 =0.532
简便计算(2.5十0.125)X8?
(2.5+0.125)*8 =2.5*8+0.125*8 =20+1 =21
2.5加0.125乘以8等于多少用
2.5+0.125*8=2.5+1=3.5
简便计算0.125x2.5x8
解答如下:简便计算的思路是,首先计算0.125X8,然后再乘以2.5即可 0.125x2.5x8 =(0.125X8)X2.5 =1X2.5 =2.5
1000\/0.04\/0.125\/8\/2.5简便运算
1000\/0.04\/0.125\/8\/2.5 =1000\/[(0.04*2.5)*(0.125*8)]=1000\/(0.1*1)=10000
(2.5x0.125)x8怎么用简便计算?
(2.5x0.125)x8 =2.5x(0.125x8)=2.5x1 =2.5
