125x198➗(18➗8)的简便运算 125x198➗(18➗8) =125x198➗(18/8) =125x198x8/18 =125x8x198/18 =1000x198/18 =1000x11 =11000

解:9000000➗25➗125➗8➗5➗4➗2 =9000000➗(25x125x8x5x4x2) =9000000➗(25x4x5x2x125x8) =9000000➗(100x10x1000) =9

列式为: 125➗(5➗8) =125➗5x8 =125x8➗5 =1000➗5 =200

1000➗(125➗16)简便是 1000➗(125➗16) =1000÷125*16 =8*16 =128
