添上括号,使下面的算式都成立.6×8+12÷4%1=52 6×...

(1)6×8+12÷(4-1),=6×8+12÷3,=48+4,=52;所以:6×8+12÷(4-1)=52;(2)(6×8+12)÷4-1,=(48+12)÷4-1,=60÷4-1,=15-1,=14;所以:(6×8+12)÷4-1=14.

(1)6×8+12÷(4-1),=6×8+12÷3,=48+4,=52;所以:6×8+12÷(4-1)=52;(2)(6×8+12)÷4-1,=(48+12)÷4-1,=60÷4-1,=15-1,=14;所以:(6×8+12)÷4-1=14.

6*(8+12)/4-1处即可

8×(6+12÷6-3) =8×(6+2-3) =8×5 =40

1.6x8+9.3÷(15.4-12.4) =12.8+9.3÷3 =12.8+3.1 =15.9

5+(7×8+12)÷4-2=20 求采纳,谢谢

一、请你口算。(8’) 0.38+0.06=0.44 (155+20)-65= 64.2+5.7= 543-27-73= 0.97-0.09=0.86 12.8-9.86= 17.05-4.58 = 9800÷25...

答案如下 5+(7×8+12)÷4-2=20

需要将第一个减号上下各加一点,变成除号,360÷{240÷(12-8)}=6

6+8+12+4-1=29
