Aquarium 1 will hold 5 small fish for every 10 gallons of water. If there are 200 gallons in the tank, you can sent up a proportion:
5 small fish/10 gallons = x small fish/ 200 gallons
if you cross multiply, you get
10x = 200 × 5
10x = 1000
x = 100
100 small fish will be in 200 gallons of water.
Aquarium 2 will hold 8 large fish for every 40 gallons of water. A proportion can also be set up here:
8 large fish/ 40 gallons = x large fish/ 200 gallons
if you cross multiply, you get:
40x = 200 × 8
40x = 1600
x = 40
40 large fish will be in 200 gallons of water.
the ratio of small fish to large fish:
100 small fish: 40 large fish
(both are divisible for 10, and if you divide both of them by ten you get)
10 small fish: 4 large fish
you can reduce again, since both are divisble by 2
5 small fish: 2 large fish
The answer is b) Estate stratification.
This stratification system was a long-run result of feudalism since it fell under the same principles:
1) There's a social hierarchy in which there were a noble class and a peasant class.
2) Only the noble class could have land ownership, and the peasant (or serf) class must work it for the noble's usufruct.
This system of stratification was upheld not only by illustrated monarchies but also by modern nation-estates (like the U.S.), this is how it received the name of estate stratification.
