Answer:

A. 1/2

Step-by-step explanation:

One way we can find which is less by comparing their decimal forms.

15/24 = 0.625

---

1/2 = 0.5

7/8 = 0.875

19/24 = 0.79

6/8 = 0.75

1/2 is the only choice that is less than 0.625, aka 15:24. Therefore, that is the answer.

Additionally, I've answered this question before.

hope this helps :)
