原式=2/11*3/4+3/11*3/4+6/11*3/4
=(2/11+3/11+5/11)*3/4
=3/4,3,=2/11*3/4+3/11*3/4+6/11*3/4=(2/11+3/11+6/11)*3/4=1*3/4=3/4,1,(2/11)*(3/4)+(3/11)/(4/3)+(6/11)*(75/100)
=(2/11)*(3/4)+(3/11)*(3/4)+(6/11)*(3/4)
=((2/11)+(3/11)+(6/11))*(3/4)
=1*(3/4)
=3/4,1,得出:四分之三,0,
=(2/11+3/11+5/11)*3/4
=3/4,3,=2/11*3/4+3/11*3/4+6/11*3/4=(2/11+3/11+6/11)*3/4=1*3/4=3/4,1,(2/11)*(3/4)+(3/11)/(4/3)+(6/11)*(75/100)
=(2/11)*(3/4)+(3/11)*(3/4)+(6/11)*(3/4)
=((2/11)+(3/11)+(6/11))*(3/4)
=1*(3/4)
=3/4,1,得出:四分之三,0,
