Three cats can eat three fish in three minutes, and three cats can eat one fish in one minute, which means one cat can eat one third of the fish in one minute.

Those two cats can eat two-thirds of the fish in one minute, and that six minutes is two-thirds times six, which is four.

But math problems are very different from reality. First of all, the size of the fish and the size of the cat didn't say. The time for small fish and big fish to eat is very different; Big cats and kittens have different appetites.

Secondly, even if a cat is as big, so is a fish. If several cats eat in the same place at the same time, there will usually be fighting and grabbing food. It is estimated that half the time in three minutes is in a state of fighting. Cats like to eat in a quiet state and will take the fish to the corner to eat alone.

Third, cats don't eat fish as honestly as Keren. If there are several fish together, they will not eat one by one honestly, but eat the parts that they think are the best, such as the stomach and internal organs of the fish. Even if 10 fish is put in, it will only take a few bites from one fish and replace it with another.

Finally, if a fish can feed a cat, even if you give it to two cats for more than half an hour, you can only eat two fish in the end.
