Answer: 630 students are not in sports during the spring season.
Step-by-step explanation:
The total number of 7th grade students at bailey middle school is 720.
15 out of 120 are in sports during the spring season. This means that out of 240 7th grade students, the number that would be in sports is 30. Therefore, the total number of students that are in sports during the spring season is
15/120 × 720 = 90 students
Therefore, the total number of students that are not in sports during the spring season is
720 - 90 = 630 students
