a swimming pool had 2.5 million liters of water in it. some water evaporates, and then the pool only had 2 million liters of water in it. what persent of water evaporated?

Respuesta :

The initial amount of water was 2.5 million liters
Then 2 million liters remained after evaporation, therefore 0.5 liters evaporated from the swimming pool.
Thus, the percentage will be given by: 0.5/2.5 × 100 = 20%
 Hence the answer is 20%

First, determine the amount of water that evaporated by subtracting the final volume of water in the pool from the initial volume. That is,

      V, evaporated = 2.5 million liters - 2 million liters
      V, evaporated = 0.5 million liters

Then, to determine the percentage of water evaporated, we divided the amount of water evaporated by the original amount and multiply the quotient by 100%.

     P = (0.5 million liters)/(2.5 million liters) x 100%
      P = 20%

Answer: 20%
