Albie is comparing the number of students wearing green to the total number of students in her class. To determine the kind of ratio relationship she is using, we need to analyze the options given.
1. Part-to-whole relationship: This means comparing a part of a group to the whole group. Albie is comparing the number of students wearing green (part) to the total number of students in her class (whole), so this option matches.
2. Whole relationship: This option is not relevant because it does not specify what is being compared.
3. Part relationship: This option refers to comparing parts of a group without considering the whole. Since Albie is considering the whole class size as well, this option is not applicable.
4. Part-to-part relationship: This option refers to comparing parts of a group to other parts within the same group. Albie is comparing the number of students wearing green to the total class size, so this option is not applicable.
Therefore, Albie is using a part-to-whole relationship to compare the ratio of students in her class who are wearing the color green to the total number of students.
