在括号里填上运算符号和数56/8=(56/4)/(8 ) 108/18=( ) /( ) (360*7)/(40 )=9 (360 )/(40/8)=9 180/15=( )/150=60/( )=( )/( )用商不变性质简便计算
56/8=(56/4)/(8/4)
108/18=(108/9)/(18/9)
(360*7)/(40 *7)=9
(360/8)/(40/8)=9
180/15=(1800)/150=60/(5)=(240)/(20)

56/8=(56/4)/(8/4 )
108/18=(90+18) /(18 )
(360*7)/(40*7 )=9
(360/8)/(40/8)=9
180/15=( 1800)/150=60/(5 )=(12 )/(1 )
