To find the average of something you add up all of the data points (in this case it would be how many pounds offish were eaten per day but this is already done for us) then you would divide by the number of points you have (the number of days which is 31). So all you have to do is 2604/31. This equals 84 pounds of fish per day on average.
the dolphin ate
2604 lbs of fish in 31 days
this can also be written as
2604/31
we want the denominator to be 1, since the denominator represents days
to do this, we can divide 31 by 31. but we must do the same to the numerator
2604 ÷ 31 = 84
so our new fraction is
84/1
so per day, the dolphin ate 84 pounds of fish
