• To maintain 6:6 ->1:1 ratio we have 5:4-> total 9 for one container for another 7:9-> total 16
  Now to maintain 1:1 ratio we can have full 9 from first container and half part that is 8 from 2nd container to make it equal in ratios.
  Answer is 9:8

• 5:4 7:9
  6:6
  (5+7)12:13(9+4) we can subtract with 6 :6===>7:5
