b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t
saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.
