Explanation

Let each container have capacity 35. First container: milk = 2/5 of 35 = 14, water = 3/5 of 35 = 21. Second container: milk = 3/7 of 35 = 15, water = 4/7 of 35 = 20. Total milk = 14 + 15 = 29. Total water = 21 + 20 = 41. Ratio milk:water = 29:41. Key is to use a common denominator or LCM to combine ratios.
