解:根据已知条件,运用去括号的规则进行列式计算:
63000÷(125x9)
=63000÷9÷125
=7000÷125
=7000÷(5x5x5)
=7000÷5÷5÷5
=1400÷5÷5
=280÷5
=56

这道题可以简便计算,运用四则运算法则,先将63000变成63*1000,再用63除以7,乘以1000除以125的商即可。解题思路如下:63000/(125*9)=63*1000/125/9=(63/9)*(1000/125)=7*8=56 谢谢

解:简便计算方法如下
63000÷(125×9)
=63000/(125×9)
=7000/125
=(1000×7)/125
=8×7
=56

先把63000写作63×1000,然后原式去括号后变成连续除以125和9,1000是125的8倍,63是9的7倍,分别相除后把商相乘,就可以口算出得数。具体计算过程如下:
63000÷(125×9)
=63×1000÷125÷9
=(63÷9)×(1000÷125)
=7×8
=56
