1/2+2/3×括号3/4%1/6.脱式计算,能简便的要简便怎...

1/2+2/3x(3/4-1/6) =1/2+2/3x3/4-2/3x1/6 =1/2+1/2-1/9 =1-1/9 =8/9 , 你好,本题已解答,如果满意 请点右下角“采纳答案”。

1/2+2/3-4/15 =15/30+20/30-8/30 =35/30-8/30 =27/30 =9/10 5/18-2/9+5/6 =5/18-4/18+15/18 =1/18+15/18 =16/18 =8/9

1/2-1/4+3/6-1/8 =1/2+3/6-(1/4+1/8) =1/2+1/2-(2/8+1/8) =1-3/8=5/8

1/2 2/3×括号3/4-1/6括号除以7/9脱式计算 解: 1/2+ 2/3×(3/4-1/6)除以7/9 =1/2+2/3×7/12÷7/9 =1/2+1/2 =1

(1/6+3/4-2/3)x12 =(2+9-8)/12x12 =2+(9-8) =2+1 =3

3.6×括号1/4+1/6-1/3括号完简便计算 解: 采用分配律, 原式=3.6x(1/4+1/5-1/3) =3.6x1/4+3.6x1/5-3.6x1/3 =0.9+0.72-1.2 =1.62-1.2 =0.42

(7/15-1/3)÷(1/3+1/5) =(7-5)÷(5+3) =1/4 (3/4+1/2)÷5/8 =3/4x8/5+1/2x8/5 =6/5+4/5 =2 2/13+3/4÷9/10+1/6 =2/13+5/6+1/6 =2/13+1 =1又2/13 [3/4-(5/8-1/4)]÷3/8 =(3/4+1/4-5/8)x8/3 =3/8x8/3 =1

你好,很高兴为你解答 一又1/24-2×括号3/8+1/6-3/4括回乘十二简便运算 具体过程如下图。

3.6×括号2/3+1/6-3/4的差 3.6×(2/3+1/6-3/4) =3.6x(5/6-3/4) =3.6x1/12 =0.3
