Question

计算：
(2(1)/(7)+3(1)/(8))−(1.375−(6)/(7))=
832(79)/(125)÷0.3  
53.3÷0.23÷0.91×16.1÷0.82=
(2014+2013×2015)/(2014×2015−1)+(2015+2014×2016)/(2015×2016−1)+(2016+2015×2017)/(2016×2017−1)+(2017+2016×2018)/(2017×2018−1)=

Answer 1

（1）（2(1)/(7)+3(1)/(8)）-（1.375-(6)/(7)）
=（2(1)/(7)+3(1)/(8)）-（1(3)/(8)-(6)/(7)）
=2(1)/(7)+3(1)/(8)-1(3)/(8)+(6)/(7)
=（2(1)/(7)+(6)/(7)）+（3(1)/(8)-1(3)/(8)）
=3+1(3)/(4)
=4(3)/(4)

（2）832(79)/(125)÷0.3
=（831+(204)/(125)）÷0.3
=831÷0.3+(204)/(125)÷0.3
=2770+(204)/(125)×(3)/(10)
=2770+(276)/(575)
=2770(276)/(575)

（3）53.3÷0.23÷0.91×16.1÷0.82
=53.3÷0.82×（16.1÷0.23）÷0.91
=65×70÷0.91
=13×5×10×7÷0.7÷1.3
=10×5×10×10
=5000

（4）(2014+2013×2015)/(2014×2015−1)+(2015+2014×2016)/(2015×2016−1)+(2016+2015×2017)/(2016×2017−1)+(2017+2016×2018)/(2017×2018−1)
=(2014+(2014−1)×2015)/(2014×2015−1)+(2015+(2015−1)×2016)/(2015×2016−1)+
