众神快来帮我填个空、小学数学题!4 = ( )/( ) = 12/( ) = ( )/5 = 28/( )5/6 = ( )/12 = 15/( ) =75/( ) = ( )/72

4=8/2=12/3=20/5=28/7
5/6=10/12=15/18=75/80=60/72

4 = ( 8 )/( 2 ) = 12/( 3) = ( 20)/5 = 28/( 7)
5/6 = ( 10)/12 = 15/( 18) =75/( 90) = ( 60)/72

4/1=12/3=20/5=28/7
5/6=10/12=15/18=75/90=60/72

按照空格顺序：
4 1 3 20 7 10 18 80 60
相信你是会做的 只是偷懒！
