Answer:
First, we have to divide the number of dead citizens by the number of the total population.
859,200/213 million
= 0.00403380281
Then, we multiply the result by 100,000 to obtain the mortality rate.
0.00403380281 x 100,000
= 403.380281.
This means that the mortality rate of citizens killed by this certain disease in 2008 is of 403,38.
