5/6减去括号,1/12加上2/15括回等于多少?

5/6÷(1/8+1/12) =5/6÷5/24 =4

5/12-(7/12+1/6)x1/2 =5/12-(7/12+2/12)x1/2 =5/12-9/12x1/2 =10/24-9/24 =1/24

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

括号5/6+3/4-1/12份括号乘以24等于多少 解:根据分配律的简便方法, 原式=(5/6+3/4+1/12)x24 =5/6x24+3/4x24+1/12x24 =20+18+2 =20+20 =40

括号负1/12+8分之3-5/6括号乘-48等于 解: (-1/12+3/8-5/6)×(-48) =(1/12-3/8+5/6)×48 =1/12×48-3/8×48+5/6×48 =4-18+40 =26

12×括号3/4-2分之1+5/6括回,简算: 12x(3/4-1/2+5/6) =12x3/4-12x1/2+12x5/6 =9-6+10 =13

1/6+1/12=1/4 1/4+1/3=7/12 1/3+2/5=11/15 3/7+3/14=9/14 1/6+3/4=11/12

(-1/2+1/6-3/8+5/12)×(-24)=12-4+9-10=7

3/4;7/12;1/5

-24×(5/6-3/8+1/12) =-24×5/6+24×3/8-24×1/12 =-20+9-2 =-13
