conversations.value: Find the answer to the math problem: The first tank is 300 liters filled while the second tank is 450 liters filled. The second tank is only 45% filled. If the two tanks have the same capacity, how many more liters of water are needed to fill the two tanks?

conversations.value: Since 450 liters represents 45%, then each 1% is equal to 450 liters/45 = 10 liters.
  Hence, the capacity of each tank is 10 liters x 100 = 1000 liters.
  So, the first tank needs 1000 - 300 = 700 liters of water more.
  While the second tank needs 1000 - 450 = 550 liters more.
  Therefore, 700 + 550 = 1250 liters of water are needed to fill the two tanks.
