Question

Suppose that in​ 2008, 703,300 citizens died of a certain disease. Assuming the population of the country is 225 ​million, what was the mortality rate in units of deaths per​ 100,000 people?

Answer 1

703300/225000000 = x/100000
multiply each side by 100000
703300/2250 = x/1

2250x = 703300
x = 313
rate is 313 per 100,000
