2018*2016/2017的简便计算

2018*2016/2017的简便计算 解:采用分配律, 原式=(2017+1)x2016/2017 =2017x2016/2017+2016/2017 =2016又2016/2017

如图

2016/2017×2018 =2016/2017×(2017+1) =2016/2017×2017+2016/2017×1 =2016+2016/2017 =2016又2016/2017

2016×2017-2015×2018 =2016×2017-2015×2017-2015 =(2016-2015)×2017-2015 =2017-2015 =2

1/2014*2015 +1/2015*2016 +1/2016*2017 +1/2017*2018 =1/2014-1/2015+1/2015-1/2016+1/2016-1/2017+1/2017-1/2018 =1/2014-1/2018 =(2018-2014)/(2014*2018) =4/(2*1007*2*1009) =1/1007*1009 =1/1016063

2018x2017-2017×2016 =2017X(2018-2016) =2017X2 =4034 希望对你有帮助,满意请及时采纳, 你的采纳是我回答的动力!

(2014+2015+2016+2017+2018)÷2016 =(2016×5)÷2016 =(2016÷2016)×5 =1×5 =5

=(2013+2019)/2016+ (2014+2018)/2016+ (2015+2017)/2016+ 2016/2016 =2+2+2+1 =7

2017×2015/2018简便计算 2017×2015/2018 =(2018-1)*(2015/2018 =2018*2015/2018-2015/2018 =2015-2015/2018 =2014又3/2018

2017*2018-2016*2019 =2017*2018-2016*(2018+1) =2017*2018-2016*2018-2016*1 =2018*(2017-2016)-2016 =2018-2016 =2 谢谢,请采纳
