5/6除以括号1/8加1/12括回

5/6÷(1/8+1/12) =5/6÷5/24 =4

琴歌(李颀)

24×括号3/8×1/6+5/12括号 =24×3/8×1/6+24×5/12 =3/2+10 =11又1/2

8x4/9等于32/9,5/9除以1/8等于乘以他的倒数8等于40/8,40/8加32/8等于9,9在乘以1.25等于11.25

=(8/15+18/60)除以1/12 =(32/60+18/60)除以1/12 =50/60除以1/12 =5/6*12 =60/6 =10

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

计算 11/12-(1/6+1/8) =11/12-7/24 =15/24 =5/8

这道题这样算, 算式12/5-2/5-1/8=1又7/8, 就是这个意思

(3/4+5/12-1/8)÷1/24 =(3/4+5/12-1/8)x24 =3/4x24+5/12x24-1/8x24 =18+10-3 =25

1/12 ÷5/6-5/8 =1/12×6/5-5/8 =1/10-5/8 =4/40-25/40 =-21/40
