Alvie is using a part-to-whole relationship when comparing the ratio of students wearing the color green to the total number of students in her class.
Alvie is using a Part-to-whole relationship when comparing the ratio of students wearing the color green to the total number of students in her class.
To determine this, we evaluate the given information: There are 30 students in her class, and 7 of them are wearing green.
In a part-to-whole relationship, we compare a part (the number of students wearing green) to the whole (the total number of students in the class).
Hence, Alvie is comparing the part (7 students wearing green) to the whole (30 students in her class), which represents a part-to-whole relationship.
