Answer 1

Teachers 4 and Students 100, Teachers 5 and Students 125

Explanation:

Going by the chart, by each teacher, the students are increasing by 25. The only ones to follow this pattern is 4:100 and 5:25

Answer 2

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
