2%6/13÷9/26+2/3 计算下面的这道题目怎样算简便就...

(2-2/3)-(12/26+9/26)

2-6/13÷9/26+2/3 =2一6/13X26/9十2/3 =2一4/3十2/3 =6/3一4/3十2/3 =2/3十2/3 =4/3

2-6/13÷9/26 = 2- (6/13)×(26/9) =2- 4/3 =2/3 . (1/3+1/4)×36 =(1/3)×36 +(1/4)×36 =12+9 =21 . 6/7×(4/5-2/3)÷1/5 =(6/7)×(4/5 - 2/3)×5 =(6/7)×(4 - 10/3) =(6/7)×(2/3) =4/7 . 3/4-3/4×4/7+9/7 =(3/4)×(1- 4/7)+9/7 =(3/4)×(3/7)+9/7 =(...

2-6/13÷9/26-2/3=2/3 【释义】 算式中先算乘除,后算加减。

=2一6/13x26/9一2/3 =2一4/3一2/3 =2一(4/3十2/3) =2一2 =0

2-6/13÷9/26-2/3=0详细过程解怎么算?在线等 =2-6/13x26/9-2/3 =2-4/3-2/3 =2-(4/3+2/3) =2-1 =1

一个式子里有加减乘除要先乘除后加减,所以这个题目要先算出中间的除法,6/13÷9/26=4/3,所以2-6/13÷9/26-2/3=2-4/3-2/3=0

2-6/13÷9/26-2/3 =2-6/13*26/9-2/3 =2-4/3-2/3 =2-(4/3+2/3) =2-2 =0

能约分的尽量约分后再计算。 2-6/13÷9/26-2/3 =2-6/13 x26/9-2/3 =2-4/3-2/3 =2-6/3 =2-2 =0
