Question

数学计算题，初一的，要过程啊，求数学学霸，有悬赏，拜托

Answer 1

1. 解：=(-1/10)+8(1/3)-11(2/3)+1/10

          =8(1/3)-11(2/3)

          =25/3-35/3

          =-3(1/3)

2. 解：=(-8/12)-1/12+3/12

          =-6/12

          =-1/2

3. 解：=(-1/3)-(3/4)-(5/6)

          =(-4/12)-(9/12)-(10/12)

               =-23/12

               =-1(11/12)

Answer 2

（1）原式=-0.1+8又1/3-11又2/3+1/10
=-3又1/3
（2）原式=-2/3-1/12+1/4
=-8/12-1/12+3/12
=-1/2
（3)原式=-1/3-3/4-5/6
=-（4+9+10)/12
=-23/12.(或者-1又11/12）

Answer 3

(-0.1)-(-8又1/3)+(-11又2/3)-(-1/10)
=-0.1+8又1/3-11又2/3+0.1
=+8又1/3-11又2/3
=-3又1/3
(-2/3)-(+1/12)-(-1/4)
=-2/3-1/12+1/4
=-8/12-1/12+3/12
=-9/12+3/12
=-6/12
=-1/2
-1/3-|+3/4|-5/6
=-1/3-3/4-5/6
=-4/12-9/12-10/12
=-23/12
=-1又11/12
