I am working on epidemiology homework: I have set up my equation based on my data as such: Incidence Rates = [60 ( # of new cases per month) / 4.

Incidence Rates = [60 ( # of new cases per month) / 4.09 * 10^6 ( Oregon population 2016) ] * 100,000 (standard population)

So written out, we have 60 divided by 4.09 times 10 to the 6th power. We then multiply this whole thing by 100,000. How do I solve this?
