If 4 out of 20 people like chocolate ice cream, what percent of the people do not like chocolate ice cream?
To find the percentage of people who do not like chocolate ice cream, we need to subtract the number of people who like chocolate ice cream from the total number of people and then express that as a percentage.
Number of people who do not like chocolate ice cream = 20 - 4 = 16
Percentage of people who do not like chocolate ice cream = (Number of people who do not like chocolate ice cream / Total number of people) x 100%
= (16 / 20) x 100%
= 80%
Therefore, 80% of the people do not like chocolate ice cream.
