Now, let's simplify each of the given ratios:

1. **15:10**:
- Simplifying: 15 ÷ 5 = 3, 10 ÷ 5 = 2
- So, 15:10 simplifies to 3:2 (not equivalent).

2. **12:24**:
- Simplifying: 12 ÷ 12 = 1, 24 ÷ 12 = 2
- So, 12:24 simplifies to 1:2 (not equivalent).

3. **14:7**:
- Simplifying: 14 ÷ 7 = 2, 7 ÷ 7 = 1
- So, 14:7 simplifies to 2:1 (equivalent).

Thus, the ratio that is equivalent to 8:4 is **14:7**.
