13 tug of war, how to divide it?

How to distribute the thirteen students in tug-of-war fairly?

We know that the tug-of-war should be fair, and both sides have equal numbers, but how can thirteen students achieve equal numbers?

For two teams to have equal numbers, they must be even, and thirteen people are odd. The number of people can't be equal, but if the number is not equal, the pursuit of equal strength, tug-of-war depends on strength. Therefore, I add one more girl to one group and one less girl to the other group. Generally speaking, the group with one more girl has more girls than the other group, and the other group has more boys than the previous group, so the strength of the two groups is basically the same.
