As an analyst for the Department of Natural Resources, you analyze samples of river water. A 2-liter sample of water contained about 24 of a particular organism and a 4-liter sample of water contained about 48 such organisms. At this rate, how many of the organisms would you expect to find in a 10-liter sample of water from the same river?
选项
答案
To answer this question you must determine the ratio of organisms to liters of river water. The problem states that a 2-liter sample of water contained about 24 organisms and a 4-liter sample of water contained about 48 organisms. Upon closer examination of this information you will see that the ratio of organisms to water is the same in each sample. Therefore, you can set up a ratio using one sample:
2 liters of water yields 24 organisms.
This can be expressed as 2 to 24, or 2:24, which can be reduced to 1:12.
For every 1 liter of water you will see 12 organisms. Therefore, 10 liters of water will contain 120 organisms.
