    The answer is 6 per m2.

    A population density is the number of animals per 1 m2.

    So, this problem can be solved by using a proportion:

    If 60 raccoons live in 10 m2, how many raccons will live in the 1 m2.

    60 raccoons : 10 m2 = x raccoons : 1 m2

    60 raccoons : 10 = x raccoons

    x raccoons = 6 raccoons

    Thus, the population density is 6 raccoons per m2.
