Answer 2

The percentage of all adults in the United States who visited a zoo in 2007 is 12%

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other, the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

So,
`x=(c*b)/(a)`

The direct rule of three can be applied in this case.

3/25 is a proportion, which says that every 25 adults in the United States, 3 visited a zoo in 2007. Then in that relationship the amount of 25 represents 100%, while the amount of 3 represents x%. Then the rule of three is applied as follows: if 25 represents 100%, what percentage represents the amount of 3?

`percentage=(3*100)/(25)`

percentage=12%

Finally, the percentage of all adults in the United States who visited a zoo in 2007 is 12%
