Aswimming pool has 2.5 million liters of water in it. some water evaporated and then the pool only has 2 millions liters in it. what percent of the water evaporated?

20% of the water evaporated

Step-by-step explanation:

We know that 500,000 evaporated because 2,500,000-2,000,000 is 500,000.

100% - 2,500,000

500,000 - x%

2,500,000/500,000 = 100/x

x=(500,000)(100)/2,500,000

x= 20%

20% of the water evaporated.
