Explanation:

Step1: Calculate the amount of decrease

The formula for the amount of decrease is \( \text{Amount of Decrease}=\text{Original Amount}-\text{New Amount} \).
Here, the original amount (number of passports in 2008) is \( 16.2 \) million and the new amount (number of passports in 2009) is \( 13.5 \) million.
So, \( \text{Amount of Decrease}=16.2 - 13.5=2.7 \)

Step2: Calculate the percent decrease

The formula for percent decrease is \( \text{Percent Decrease}=\frac{\text{Amount of Decrease}}{\text{Original Amount}}\times100\% \)
Substitute the values: \( \text{Percent Decrease}=\frac{2.7}{16.2}\times 100\% \)
\( \frac{2.7}{16.2}=\frac{27}{162}=\frac{1}{6}\approx0.167 \)
\( 0.167\times100\% = 16.7\% \)

Answer:

\( 16.7\% \)
