These are cells that have a nucleus and organelles bounded in a plasma membrane. Examples of these organisms include humans, protozoa, fungi, plants and other animals.

Number of fossils collected over period 1:

400

Number of fossils collected at a later period :

204

For each display case to have the same number of fossils ; the greatest number of fossils possible per case:

Obtain the greatest common factor of both 400 and 204

400 = 1, 2, 4, 5, 8, 10, 25, 40, 50, 80, 100, 200, 400

204 = 1, 2, 3, 4, 6, 12, 17, 34, 51, 102

Hence, the greatest common factor (400 and 204) is 4

Hence, the greatest Number of Fossil possible per case = 4
