1、6.4×0.125+3.6÷8 2、36×1.16+3.6×13.4 怎样简便...

6.4*8+3.6÷0.125=6.4*8+3.6*8=(6.4+3.6)*8=10*8=80 希望我的回答对您有帮助,有问题可以追问.满意请及时采纳,谢谢!

8)=6.4x8+6x8=(66.4*8+3.6/0.125=6.4x8+6/(1/.6)x8=10x8=80希望对你有帮助.4+3

6.4*3.6+3.6*3.6=(6.4+3.6)*3.6=10*3.6=36

原式等于0.125*(13.6-3.6)=0.125*10=1.25所以原式的计算结果为1.25

3.6*0.125+6.4*1/8=3.6*0.125 +6.4*0.125 =10*0.125=1.25

0.125*8=1再用6.4+3.6=10再用10÷1

13.6*0.125-3.6÷8=13.6*0.125-3.6*0.125=0.125*(13.6-3.6)=0.125*10=1.25

8.9*3.6+3.6*0.1+3.6=3.6*(8.9+0.1+1)=3.6*10=36

(6.3x6.4+6.3x3.6)÷1.4=(6.4+3.6)*6.3÷1.4=10*(6.3÷1.4)=10*4.5=45

解:简便计算13.6x0.125-3.6÷8=13.6x0.125-3.6x0.125=0.125x(13.6-3.6)乘法分配律=0.125x10=1.25祝学习进步.
