The problem states:

"At a track and field competition, there are 12 sprinters and 14 long-distance runners and 12 fans. All teams need to have the same number of sprinters and the same number of long-distance runners.

What is the greatest number of teams that can be formed?"

The answer is "The greatest number of teams that can be formed is 2 teams", but this is rather implausible. Isn't is more sensible to say that the greatest number of teams than can be formed is TWELVE with one long distance runner and one sprinter each.

Also, the answer given says "...with 6 sprinters and 7 long-distance runners each." Yet, the instructions state, "All teams need to have the same number of sprinters and the same number of long-distance runners."

Thus, I want to ask you since when 6 = 7? Maybe you should spend more time on quality assurance.
