Question

Mr. Howard surveyed his students about their favorite flavor of ice cream. In his second period class, 725 preferred vanilla. In his fourth period class, 8 out of 27 students preferred vanilla. In his sixth period class, 30% preferred vanilla. In which class did the greatest fraction of the students prefer vanilla ice cream?

Answer 1

8/27.

Explanation:

To find out which class had the greatest fraction of students who preferred vanilla ice cream, we need to compare the ratios of students who preferred vanilla to the total number of students in each class.

For second period class:

Number of students who preferred vanilla = 725

Total number of students = unknown

Ratio of students who preferred vanilla to total number of students = unknown/unknown = undefined

For fourth period class:

Number of students who preferred vanilla = 8

Total number of students = 27

Ratio of students who preferred vanilla to total number of students = 8/27

For sixth period class:

Number of students who preferred vanilla = 30% of total number of students

Total number of students = unknown

Ratio of students who preferred vanilla to total number of students = 0.3*unknown/unknown = 0.3

Therefore, the fourth period class had the greatest fraction of students who preferred vanilla ice cream, with a ratio of 8/27.
