Answer:

120.35

Explanation:

De tanque lleno de agua,se utilizan las dos quintas partes y luego los tres cuartos del resto. Si aún quedan 240 litros ¿cuántos litros tiene?

2/5- 3/4=-0.35

tienes 120 galones más el 0.35

120+0.35=120.35

que tengas un buen día!!!!!!!!!!!!!

The initial amount of water in the tank was 1600 liters.

Let's denote the initial amount of water in the tank as W.

First, two-fifths of the water are used, leaving
\((3)/(5)\) of the water remaining.


\[\text{Remaining amount} = (3)/(5) * W\]

Then, three-quarters of the remaining water are used, leaving \(\frac{1}{4}\) of the remaining water.


\[\text{Final amount} = (1)/(4) * \left((3)/(5) * W\right)\]

According to the problem, the final amount is 240 liters:


\[(1)/(4) * \left((3)/(5) * W\right) = 240\]

Now, solve for W:


\[(3)/(5) * W = 240 * 4\]


\[(3)/(5) * W = 960\]


\[W = (960 * 5)/(3)\]


\[W = 1600\]

So, the initial amount of water in the tank was 1600 liters.
