Albie is using a part-to-whole ratio relationship.
Albie is using a part-to-whole ratio relationship. She is comparing the number of students wearing the color green (the part) to the total number of students in her class (the whole).
To determine the ratio of students wearing the color green to the total number of students in her class, Albie should divide the number of students wearing green by the total number of students.
In this case, Albie finds that out of 30 students in her class, 7 are wearing green. So the ratio would be 7 green students out of 30 students in total.
To express this as a ratio, it can be written as 7:30 or simplified as 1:4.
Therefore, Albie is using a ratio relationship of 1:4, where for every 1 student wearing green, there are 4 students in total.
