We know that the people ratio is 5 seagulls : 2 crabs meaning there are a total of 7 animals per grouping (5 seagulls + 2 crabs).
We then know that there 2 crabs per every 7 animals. Since we know there are 70 crabs, we can calculate the total animals as 7/2 * 70 = 245.
We also know that there 5 seagulls per every 7 animals. Then to calculate total seagulls we take 245 * 5 / 7 = 175 seagulls.
We know that the people ratio is 2 sheep : 3 pigs : 4 goats. This means there are a total of 9 animals per grouping (2 sheep + 3 pigs + 4 goats).
We then know that there 2 sheep per every 9 animals. Since we know there are 12 crabs, we can calculate the total animals as 9/2 * 12 = 54.
There are 4 goats per every 9 animals. To calculate total goats we take 54 * 4 / 9 = 24 goats.
