Question: 1 / 400

If a tank can hold 2,000 liters, and it is currently filled to 1/4 of its capacity, how many liters are left to fill?

1,000 liters

1,500 liters

To determine how many liters are left to fill in the tank, first calculate how much water is currently in the tank. Since the tank holds a total of 2,000 liters and is filled to 1/4 of its capacity, you can calculate the current volume of water as follows:

1. Find 1/4 of 2,000 liters:

\[

\frac{1}{4} \times 2,000 = 500 \text{ liters}

\]

This means there are currently 500 liters in the tank.

Next, to find out how much more water can be added to reach full capacity, subtract the current volume from the total capacity:

\[

2,000 \text{ liters} - 500 \text{ liters} = 1,500 \text{ liters}

\]

Therefore, there are 1,500 liters left to fill the tank to its full capacity. This calculation confirms that the correct answer is based on a simple understanding of fractions and subtraction applied to the total tank capacity.
