找规律填空:1/12,1/6,1/4,1/3,5/12,1/2,().
6-(1/2+3/4-5/12)?
12 1 2 6 15 1 5 3 ()2 6 2后面怎么填
5/12-1/6+2/3=?
找规律填空.1/2,1/3,5/6,(),12/6,()
1/2+3/2:;1/6+5/6;1/12+7/12;1/20+9/20:第五个是( )
数学计算题(3+5/9-2/3)×(1/6+1/9+1/12)-(1/6-1/9+1/12)×3+(1/6+1/9+1/12)×(2/3-5/9)谢谢来答
(12m+1)(2m-3)-(6m+5)(6m+5)

1/6、1/3、1/2( )、5/6、1.
7/5x5/6-5/7除以6/5 12X(3/4-5/12+1/6) (7/8-5/16)除以(1/2+1/6) = = =能简算的要简算7/5x5/6-5/7除以6/5= 12X(3/4-5/12+1/6)= 7/8-5/16)除以(1/2+1/6) =
45*(2/5+3/10) 5/12*1/6+7/12除以6 4/5除以(5/6除以5/12) 脱式计算如题
1/2 + 1/6 + 1/12 + 1/20 + 1/30+ 1/42 + 1/56 + 1/72=(1+ 1/2+ 1/3+ 1/4+ 1/5)×(1/2+ 1/3+ 1/4+ 1/5+ 1/6)-(1+ 1/2+ 1/3+ 1/4+1/5+ 1/6)×(1/2+ 1/3+ 1/4+ 1/5)
(1)120+290÷58*16 (2)5/6*11+5/6 (3)(2/3-2/5)*(1/8+1/12)简算
能简算的要简算 (5)(5+5/8)×3/5 (6)12×(2/11-1/12)×11(5)(5+5/8)×3/5(6)12×(2/11-1/12)×11
