It takes 3 hours for the cats to catch 27 fish in the pond.

How long did it take them to catch 27 fish in all?

Zarko can catch 5 fish per hour.

Manchu can catch 2 fish every 0.5 of an hour, so in an hour, the cat would catch 2 times that, which is 4 fish.

When working together, the cats can catch 4 + 5 = 9 fish per hour

If the cats work for x hours, then they catch 9*x fish.

To get the time that takes them to catch 27 fish we just need to solve the linear equation:

9x = 27

Solving for x:

x = 27/9 = 3

It takes 3 hours for the cats to catch 27 fish in the pond.
