The Golden Lion Tamarin is a very endangered primate that lives in South America. There are only about 600 left in the wild! Our zoo happens to have 9 males, 15 females and a few babies. We want to put the tamarins into the greatest number of displays possible with the same number of males in each display and the same number of females in each display. How many displays can we make if all of the Golden Lion Tamarins are displayed?

The Roosevelt Elk live in the western part of North America and on some of the Alaskan islands. These are a very large member of the deer family weighing as much as 875 pounds! We have 10 males and 25 females. If we create as many identical herds as possible, how many females will be in each herd?

Siamangs (SEE-uh-mangs) are one of the lesser known apes. (no tail - not monkey!) They live on the island of Sumatra (Indonesia) and eat approximately equal amounts of leaves and ripe fruit. They are also known to ingest insects, birds and bird eggs. We have 42 pounds of cabbage (and spinach) and 36 pounds of fruit. We will divide the food into the greatest number of identical meals possible with the same amount of cabbage (and spinach) in each meal and the same amount of fruit in each meal. How many meals can we make if all of the food is used?

The White-Naped Crane lives in the eastern Asia and Japan. These large birds (10 - 14 pounds) are mostly vegetarians in the wild and while their life-span in the wild is unknown, there was one that lived for 45 years in the zoo! At our zoo they are fed crickets and grapes. We try to keep their meals as identical as possible. We have 40 pounds of grapes and 16 pounds of crickets. What is the greatest number of identical meals that we can make?

Red-flanked duikers are among the smallest antelope species. They live in along the forest edges in Africa. They have a particularly amazing body shape (wedged) that enables them to jump quickly into thick brush and cover. Their bodies are designed to split the bushes and enable them to pass. We have 4 males, 9 females and 3 babies. We want to make as many identical herds as possible with the same number of males in each herd and the same number of females in each herd. How many herds will we be able to make if we use all of our specimens?

The San Francisco garter snake is a beautiful snake, with dramatic blue, black and red stripes running down the length of the body. They are an endangered subspecies of the common garter snake. In the wild, these snakes eat amphibians (including tadpoles), earthworms, small fish. As a defense against predators, these snakes can make themselves smell and taste bad! We have 18 ounces of small fish and 72 ounces of worms to feed our garter snakes. What is the greatest number of identical meals that can be made while using all of our food?
