7. 23:30 = \boxed{} p.m.

Explanation:

Step1: Convert 20:00 to 12-hour format

Subtract 12 from hours: $20 - 12 = 8$, so $20:00 = 8$ p.m.

Step2: Classify 8 p.m. time period

8 p.m. falls in the evening (typically 6 p.m. to 12 a.m.).

Step3: Convert 13:25 to 12-hour format

Subtract 12 from hours: $13 - 12 = 1$, so $13:25 = 1:25$ p.m.

Step4: Classify 1:25 p.m. time period

1:25 p.m. falls in the afternoon (typically 12 p.m. to 6 p.m.).

Step5: Convert 15:45 to 12-hour format

Subtract 12 from hours: $15 - 12 = 3$, so $15:45 = 3:45$ p.m.

Step6: Classify 3:45 p.m. time period

3:45 p.m. falls in the afternoon (typically 12 p.m. to 6 p.m.).

Step7: Convert 23:30 to 12-hour format

Subtract 12 from hours: $23 - 12 = 11$, so $23:30 = 11:30$ p.m.

Step8: Classify 11:30 p.m. time period

11:30 p.m. falls in the night/evening (typically 6 p.m. to 12 a.m.).
