8/7-4/13×1/2-11/13脱式计算怎么算？

Answer 1

直接按照四则运算顺序来算比较麻烦，而运用运算性质，则可以使计算简便。
8/7-4/13×1/2-11/13
=8/7-2/13-11/13
=8/7-(2/13+11/13)
=8/7-13/13
=8/7-1
=8/7-7/7
=1/8
(第三步和第五步都是可以省略的)

Answer 2

8/7-4/13×1/2-11/13的脱式计算方法是：
8/7-4/13×1/2-11/13
=8/7-2/13*1-11/13
=8/7-1
=1/7
这就是8/7-4/13×1/2-11/13的脱式计算方法，结果等于1/7。

Answer 3

8/7-4/13×1/2-11/1
=8/7-4/13×1/2-11/1
=7/8-2/13-11
=91/104-16/104-11
=75/104-11
=75/104-104/104-10
=-29/104-10
=-10又29/014

Answer 4

8/7-4/13×1/2-11/13
=8/7-2/13-11/13
=8/7-（2/13+11/13）
8/7-1
=1/7

Answer 5

原式可以变化为
8/7-(4/26+22/26)
=8/7-1
=8/7-7/7
=1/7
