12.5乘0.32乘25

12.5*0.32*25=12.5*0.4*0.8*25=(12.5*0.8)*(25*0.4)=10*10=100 要注意:25*4=100 125*8=1000

0.32*25*12.5=0.4*25*0.8*12.5=10*10=100

(12.5*0.8)*(25*0.4)

等于100

12.5乘【0.8乘0.4】乘0.25 =12.5乘0.8+0.4乘0.25 下面自己算吧

12.5*0.7*0.32*25 =12.5*0.7*0.4*0.8*25 =(12.5*0.8)*0.7*(0.4*25) =10*0.7*10 =70 同学,提醒一下,在获得答案后,别忘了及时采纳哦,采纳可获得2经验值奖励!请抽空采纳,谢谢!顺祝春节快乐,学习进步,万事顺利!提前祝元宵节快乐!
