4P + 2C= 20 (the number of legs), and

C = P/2 (since 1/3 are chickens)

Therefore

4P + P = 20
P = 4 is the number of pigs, and
C = 2

To find the number of pigs, we need to determine the number of chickens first.

Let's assume the total number of barn animals is represented by 'x'. Since 1/3 of the animals are chickens, we can calculate the number of chickens as (1/3) * x.

Next, we need to calculate the number of pigs. Since the remaining animals are pigs, their count is (2/3) * x.

Now, we know that each chicken has 2 legs and each pig has 4 legs. As there were a total of 20 legs in the barn, we can write the equation:

(2 * (1/3) * x) + (4 * (2/3) * x) = 20

Simplifying this equation will give us the value of 'x', which represents the total number of barn animals. From there, we can calculate the number of pigs.
