The table gives the numbers of teachers and students in grades 6 to 8 at earhart middle school. grade teachers students 6 1 25 7 2 50 8 3 75 which teacher-to-student ratio maintains the proportional relationship described in the table?

Rewriting the table:

Grade          Teachers           Students
    6                     1                        25
    7                     2                       50
    8                     3                       75

Grade 6 to 8 all maintained the same proportional relationship because for every one teacher, there's 25 students 

This is a robot. try again lol. maybe you attached the wrong image.
