(1/3-1/4)÷1/8+5/6= 8(1/3-1/4)+5/6=16/6-2+5/6=9/6=3/2。
8-5/9-9/1*4 =?此题似应是8-5/9-9/(1*4) =?(网络传送时最易引起误解,产生岐意),
8-5/9-9/(1*4) =8-2-5/9-1/4 =5+3/4-5/9=5+7/36。
(1/2-1/3+1/6)*24 =24/2-24/3+24/6=12-8+4=16。
4/9÷{4/5-(1/5+1/3)}=4/9÷{(12-3-5)/15}=4/9×15/4=5/3。

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

8-5/9-9/1*4
=8-5/9-4/9
=8-(5/9+4/9)
=8-1
=7

(1/2-1/3+1/6)*24
=1/2×24-1/3×24+1/6×24
=12-8+4
=8

4/9÷{4/5-(1/5+1/3)}
=4/9÷{4/5-1/5-1/3}
=4/9÷{3/5-1/3}
=4/9÷4/15
=4/9×15/4
=5/3
