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

计算: 2018x 2016/2017 =(2017+1)x2016/2017 =2016+2016/2017 =2016又2017分之2016

简便计算2018+2017-2016 2018+2017-2016=2018+(2017-2016) =2018+1=2019

(201720172017-20172017-2017)/(201820182018-20182018-2018) =[2017×(100010001-10001-1)]/[2018×(100010001-10001-1)] =2017/2018

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

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

2018*2016/2017=(2017+1)*2016/2017=2016+2016/2017=2017-1/2017

2017分之2016和2018分之2017比大小多种方法: 2016/2017=1-1/2017,2017/2018=1-1/2018,1/2017>1/2018,2016/2017<2017/2018; 2016/2017=(2016*2018)/(2017*2018),2017/2018=(2017*2018)/(2017*2018),(2016*2018)<(2017*2018)...

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!
