How do you tabulate a survey result if the answers are more than one?

for example, there are 5 people asked but only 4 answered. how do we compute the percentage of response-based on number of people or based on number of answers?

Uhhhhhhhh....burritos.





Let's see. Better yet, let's "tabluate":





(Example):





(1) - No response (20%)


(2) - Response 1 (40%)


(1) - Response 2 (20%)


(1) - Response 3 (20%)





That is the greatest tabulation ever!
