3.25剩47加5.3剩32.5 =3.25x47+3.25x53 =3.25x(47+53) =3.25x100 =325 请采纳正确答案,你们只提问,不采纳正确答案,回答都没有劲!谢谢管理员推荐采纳!! 朋友,请【采纳答案】,您的采纳是我答题的动力,如果没有明白,请追问。谢谢。

48+47-46-45+44···+4+3-2-1脱式计算简便怎么写 48+47-46-45+44···+4+3-2-1 =【48-46+47-45】+...+【4-2+3-1】 =4*12 =48

解: 47/6*(39/10)+13/6*3.9 =47/6*3.9+13/6*3.9 =(47/6+13/6)*3.9 =60/6 *3.9 =10*3.9 =39
