1,2015÷2015又2015/2016

2015÷2015又2015/2016 =2015÷(2015+2015/2016) =1÷(1+1/2016) =1÷2017/2016 =2016/2017

2015×(2015×2016+2015)分之2016+2017分之1 =2015×(2015×2017)分之2016+2017分之1 =2017分之2016+2017分之1 =1

2015/2015又2016分之2015+2017分之1怎样计算 2015/2015又2016分之2015+2017分之1 =2015÷(2015+2015/2016)+1/2017 =1÷(1+1/2016)+1/2017 =2016/2017+1/2017 =1

2014除以2014又2015分之2014+2016分之1 =2014÷(2014又2014/2015)+1/2016 =2014÷(2014+2014/2015)+1/2016 =1÷(1+1/2015)+1/2016 =1÷(2016/2015)+1/2016 =2015/2016+1/2016 =1

2015+2014x2016÷2015x2016-1 =2015+2014x2016/2015x2016-1 =2014+(2015-1)x(2015+1)x2016/2015 =2014+(2015^2-1)x2016/2015 =2014+2015^2x2016/2015-2016/2015 =2014+2015x2016-2016/2015 =2014+4062240-1又1/2015 =4064254一1又1/2015 =4064252...

1÷(1×2)+1÷(2×3)+1÷(3×4)+……+1÷(2015×2016) =(1-2分之1)+(2分之1-3分之1)+(3分之1-4分之1)+......+(2015分之1-2016分之1) =1-2分之1+2分之1-3分之1+3分之1-4分之1+......2015分之1-2016分之1 =1-2016分之1 =2016分2015

题目应该是: 1÷(1×2)+1÷(2×3)+1÷(3×4)+1÷(4×5)+……+1÷(2015×2016) =(1/1-1/2)+(1/2-1/3)+(1/3-1/4)+(1/4-1/5)+...+(1/2015-1/2016) =1/1-1/2016 =2015/2016

2015÷2015又2016分之2015十2017分之1 =2015÷(2015+2016分之2015)十2017分之1 =1÷(2015÷2015+2016分之2015÷2015)十2017分之1 =1÷(1+2016分之1)十2017分之1 =2017分之2016十2017分之1 =1

(-2又2015/2016)÷1/2016 =(1/2016-3)x2016 =1/2016x2016-3x2016 =1-6048 =-6047
