Step-by-step explanation:
Given that tank A's volume is 550 gallons and that it has a capacity ratio of 11:15 - that means that Tank B's total volume is 403.33 Gallons.
Then knowing that Tanks A & B are at 2 different Water Capacities - 66% for Tank A & 53% for Tank B - you take the total volumes & multiply by the percentages to find that Tank A has a Volume of 363 gallons of water inside of it and that Tank B has 213.77 gallons of water.
