125x48的简便方法怎样做

125×48 =125×8×6 =1000×6 =6000 希望我的回答对您有帮助,有问题可以追问。 满意请及时采纳,谢谢!

解: 125x48 =125x8x6 =(125x8)x6 =1000x6 =6000

先算:125×8=×X再算:125×40=XX然后第一个xxX第二个xx=得数

125x48 =125x(8x6) ==125x8x6 =1000x6(乘法结合律) =6000

125x48 =125×8×6 =(125×8)×6 =1000×6 =6000 乘法分配律。

125X25X48简便方法 =125x8x6x25 =1000x150 =150000

125x25x48 =125x48x25 =125x8x6x25 =(125x8)x(6x25) =1000x150 =150000

125×48 =125×8×6 =1000×6 =6000

125x48x5 =125X8x6x5 =1000x30 =30000

24x25 =6×(4×25) =6×100 =600 125x48 =125×8×6 =1000×6 =6000
