Average kills to deaths will be 1 80 kills 80 deaths. Average kill death ratio is adding up the kill death ratios then dividing it by the amount of players. The average kill death ratio of the above is 1.09. If i kill you 5 times and you kill me once my kill death ratio is 5 and yours is 0.20.. the average of the kill death ratios is 5 + 0.2 which is 5.2 then divided by 2 which is 2.6. That is the average of our kill death ratios.
