Question 760147
The water plus the 12% alcohol must sum to 6 liters.  Let v = liters of the water. Let p = the amount liters of the 12% alcohol solution.


{{{(12p)/(p+v)=10}}} and {{{p+v=6}}}, so the rational equation can be stated as {{{highlight(12p/6=10)}}}.  
{{{p=(6/12)10=5}}}.


5 liters of the 12% alcohol, and 1 liter of water.
