It depends what your trying to get close to. If your trying to get close to a number that is easier to work with 1 4/8 is good because its the same as 11/2 but the closest whole number is 1.

The correct answer is:

18.

Explanation:

There were 303 people surveyed total.

There were 64 people with brown eyes and black hair; that makes the percentage of the population 64/303 = 21.12% ≈ 21%.

There were 9 people with blue eyes and black hair; that makes the percentage of the population 9/303 = 2.97% ≈ 3%.

This means the percentage of students with brown eyes and black hair was greater than the percentage of students with blue eyes and black hair by:
21-3 = 18%.
