Steve screamed 12 times in 15 minutes.  Divide the number of time intervals (15) by the number of times the action happened (12).  Your formula will have the number 15 over the number 12.

15
12    =  1 and 3/12  = 1 and 1/4.

Now what does that mean?

It means that Steve screamed once every minute and a quarter (minute and 15 seconds) on the average.  This is the "average" that you will try to decrease with your interventions.
