(6-27÷18)×2/9能简算吗
(6-27÷18)×2/9能简算吗
1、如果18*6=18÷6+2,那么27*9=( );
(1)9/2÷27=6/2÷18=3/2÷9=1/2÷()=()÷()=
(1×2×4+2×4×8+3×6×12)÷(1×3×9+2×6×18+3×9×27)
(1*6*9+2*12*18+3*16*27+...+100*600*900)÷(1*2*3+2*4*6+3*6*9+.
1+1+8+9+6+9+18+39*380-27+12232÷32-87=?
27又18/19÷9
(1×2×4+2×4×8+3×6×12+……+6×12×24)÷(1×3×9+2×6×18+3×9×27+……+6×18
解方程:2/9÷18=1/6x
2/3x÷3/4=18 2-6/13÷9/39-2/3
(51分2+18分5)乘以9乘以17能简算吗
(2÷3÷7+4÷6÷14+14÷21÷49)÷(4÷7÷9+8÷14÷18+28÷49÷63)=?
