There are approximately 3.2
million deaths per year in country a. express this quantity as deaths per minute.

So, using the number 3,200,000 deaths per year, you want to divide it until it reaches deaths per minute.
3,200,000 divided by 365 (for days)
8767.123 divided by 24 (for hours)
365.297 divided by 60 (for minutes)
and so you get 
6.088 deaths per minute

Hope this helped.
