Answer:
The answer is B.
Explanation:
There isn't much to explain.
3/6 people like chocolate ice cream and x/600 where x is the number of people who like chocolate ice cream.
Cross multiply to solve for x.
6*x = 3*600
6*x = 1800
x = 300
300 people like chocolate ice cream so about half of people like chocolate ice cream compare to 3/6 the same.
