Respuesta :

Answer:

This population, the population is 45 fish.

Step-by-step explanation:

This problem can be solved by a rule of three.

Last year there were 60 fish in the lake. That was 100, that is, decimal 1.

This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So

60 fish - 1

x fish - 0.75

x= 60*0.75

x=45

This population, the population is 45 fish. Please make the brainliest.
