8 liters of water were poured into two tanks, filling each of them by two-thirds.

8 liters of water were poured into two tanks, filling each of them by two-thirds. How many liters of water will go into these tanks if they are filled to the top.

Let us determine to what number of liters the capacity of one such tank corresponds, if we know, on the basis of data from the conditions of this assignment, that eight liters are only 2/3 of its capacity:

8: 2/3 = 12.

Let’s calculate how many liters the total capacity of the tanks corresponds to, if we know that there are two such tanks:

2 * 12 = 24.

Let’s determine how much more you can add to them:

24 – 8 * 2 = 8.

Answer: The total capacity of the two tanks is 24 liters. You can add another 8 liters to them.
