13/18。 1/6×括号5-2/3括号等于多少的解答过程如下: 1/6×(5-2/3) =1/6×(15/3-2/3)(这里把5进行通分) =1/6×13/3(同分母的分数减法) =13/18(分数的乘法) 扩展资料: 通分的步骤: 1. 先求出原来几个分数(式)的分母的最简公分母; 2. ...

先算括号里的,再算括号外的

(36/5+36/7)÷(2/5+2/7) =18×(2/5+2/7)÷(2/5+2/7) =18÷1 =18

5/16 ×[(2/5+2/3)÷5/6] = 5/16 ×[16/15×6/5] =5/16 ×16/15×6/5 =2/5

2.1×括号6.5-4.5括号除以8.4等于0.5 2.1×(6.5-4.5)÷8.4=0.5 验算: 2.1×(6.5-4.5)÷0.5 = 2.1×2÷0.5 =4.2÷0.5 =8.4

12/5×括号5/6+1/2括号减0.8 =(12/5)×(5/6+1/2) -0.8 =(12/5)×(8/6) -0.8 =16/5 - 0.8 =3.2-0.8 =2.4
