Answer:
2 sections.
Explanation:
Given that number of students that had homework last night = 8
Given that number of students that had not homework last night = 4
Then total number of students = 8+4= 12
Then fraction of students that had not homework last night = 4/12
Alaina used that data to design a spinner with 6 congruent sections.
Then number of sections of Alaina's spinner the represents students who did not have homework = ( 6 section) ( 4/12 fraction)
= 6(4/12)
=24/12
=2
Hence final answer is 2 sections.
