1)1/12,1/6,1/3, 2/3 ,4/3, 8/3 前项×2
(2)27/64,9/16,3/4, 1 ,4/3 16/9 前项×4/3
1/12X2=1/6,1/6X2=1/3,1/3X2=2/3,2/3X2=4/3
27/64X4/3=9/16,9/16X4/3=3/4,3/4X4/3=1,
1X4/3=4/3
48*(1/12+1/6-3/4)
(-1/6+3/4-1/12)*(-48)
(-1/12-1/36+3/4-1/6)×(-48)
(3/4-1/6-1/12-1/36)×(-48)
(-1/12-1/36+3/4-1/6)*(-48)
(-1/6-1/16+3/4-1/12)*(-45)
12x(4/1十6/1—3/1)

2/1 3/1 4/1 5/1 6/1 8/1 10/1 12/1 15/1 20/1
计算:1/6-(+1/3)-(-1/12)
1/6+7/12*(3/4-1/6)怎么算
找规律填空:1/12,1/6,1/4,1/3,5/12,1/2,().
按规律写数:1/12,1/6,1/4,1/3,5/12,1/2,( )
(5/12+1/6-3/4)×(-24)
填空:1,3,2,6,4,(),(),12,(),
12×1/2+6×4/3,=
1/3+2/6+4/12=
递等式计算 1/2-1/3+1/4-1/5+1/6-1/12
