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?
Since 450 liters represents 45%, then each 1% is equal to 450 liters/45 = <T>divide(450, 45)=10.0 liters.
Hence, the capacity of each tank is 10 liters x 100 = <T>multiply(10, 100)=1000 liters.
So, the first tank needs 1000 - 300 = <T>subtract(1000, 300)=700 liters of water more.
While the second tank needs 1000 - 450 = <T>subtract(1000, 450)=550 liters more.
Therefore, 700 + 550 = <T>add(700, 550)=1250 liters of water are needed to fill the two tanks.
