25.25*0.65*4/0.65怎样简便计算

25.25*0.65*4/0.65怎样简便计算
25.25*0.65*4/0.65
=25.25*4*0.62/0.62
=(25*40+0.25*40)*(0.62/0.62)
=(1000+10)*(1)
=1010

   25.25×0.65×4÷0.65
  =(25+0.25)×4×0.65÷0.65(×0.65÷0.65相互抵消)
  =(25+0.25)×4
  =(25×4)+(0.25×4)
  =100+1
  =101
  不信就用计算器算 25.25×0.65×4÷0.65

25.25*0.65*4/0.65
=25.25*4
=101

25.25×0.65×4÷0.65=25×4×1.01×(0.65÷0.65)=100×1.01×1=101

25.25*0.65*4/0.65
=25.25*4*0.65/0.65
=25.25*4
=25*4+0.25*4
=100+1
=101

25.25*0.65*4/0.65
=25.25*4*0.65/0.65
=25.25*4
=25*4+0.25*4
=100+1
=101
呵呵,大概这样吧!请采纳。。谢谢

25.25*0.65*4/0.65
=25.25*4*0.65/0.65
=25.25*4
=25*4+0.25*4
=100+1
=101

25.25*0.65*4/0.65
=25.25*4
=101
