2015*2015/2016简便计算方法

2015*2015/2016简便计算方法 2015*2015/2016 =2015*(1-1/2016) =2015-2015/2016 =2014又1/2016

2015/2016×2015 =2015/2016×(2016-1) =2015/2016×2016-2015/2016×1 =2015-2015/2016 =2014又1/2016

怎样简便计算 2015×2015/2016 =(2016-1)×2015/2016 =2016×2015/2016-2015/2016 =2015-2015/2016 =2014又1/2016

答:2015/2015又2016/2015+1/2017 =2015*2016/(2015*2017)+1/2017 =2017/2017 =1

2016×2014/2015 =2015×2014/2015+1×2014/2015 =2014又2015分之2014

(2016-1)*2015/2016=2016*2015/2016-2015/2016=2015-2015/2016=2014又1/2016

2017x2016/2015 =2017x(1+1/2015) =2017+2017x1/2015 =2017+2017/2015 =2018又2/2015

2014*2016*(2014*2015/1+2015*2016/1) =2014×206×(2014×2015+2015×2016) =2014×2016×2015(2014+2016) =2014×2016×2015²×2 =(2015-1)(2015+1)×2015²×2 =(2015²-1)×2015²×2 =2×(2015^4-2015²) =2×(164854...

=2017分之2016×(2017-1) =2017分之2016×2017-2017分之2016×1 =2016-2017分之2016 =2015又2017分之2016 你好,本题已解答,如果满意 请点右上角“采纳答案”。
