The large rectangular tank shown is 4/5 filled with water. The water is then poured into the smaller rectangular container until it is full. How much water is left in the tank
We could answer this more accurately if we knew the sizes of the tanks.

To determine how much water is left in the tank after pouring it into the smaller container, we need to understand how the volumes of the two containers are related.
Let's assume the large rectangular tank has a volume of V1 and the smaller rectangular container has a volume of V2. We know that initially, the large tank is 4/5 filled with water. Therefore, the volume of water in the large tank is V1 * (4/5).
Next, we pour all the water from the large tank into the smaller container. Since the smaller container is full, its volume V2 will equal the volume of water poured into it.
Therefore, the amount of water left in the tank is equal to the difference between the initial volume of water in the large tank and the volume of the smaller container:
Water left in tank = (Initial volume of water in large tank) - (Volume of smaller container)
= V1 * (4/5) - V2
Without specific measurements or values for V1 and V2, we cannot provide an exact numerical answer. However, by knowing the respective volumes of the two containers, you can substitute the appropriate values into the formula to calculate the water left in the tank.
