Calculate:  1 year __?__How many minutes?_______?

1 year = 365 days;

1 day = 24 hours;

60 minutes = 1 hour. 
________________________________
So:  To calculate many minutes in 1 yr.
_______________________________________
  1 yr * (365 d/ yr) * (24 h /d) *  (60 min/ h) =  (365)*(24)*(60)  min. ;
______________________________________________________
     1 year = (365)*(24)*(60)  min. = 525,600 min.
_____________________________________________
   (3.5 million deaths / 1yr) * (1yr / 525,600 min)  =

(3.5 million deaths / 525,600 minutes) =

(3.5 million) / (525,600)   deaths per minute;

Note:  "3.5 million = 3,500,000" ; 
 
3,500,000 / 525,600 = 6.6590563165905632
                                                        →  round to "6.7" ;
                                                        → {use 2 (TWO) significant figures};

The answer is:  6.7 deaths per minute .
