Albie is using a part-to-whole relationship when comparing the ratio of students wearing green to the total number of students in her class.
Albie is using a part-to-whole relationship to compare the ratio of students wearing green to the total number of students in her class. In this case, the "whole" refers to the total number of students in her class (30), and the "part" refers to the number of students wearing green (7). By comparing the part (7) to the whole (30), Albie can determine the ratio of students wearing green to the total number of students.
