Proposed solution
To determine the percentage of students enrolled in hip-hop dance, let's follow these steps:
1. **Total number of students in the class:**
\[
20 \text{ students}
\]
2. **Percentage enrolled in contemporary dance:**
\[
20\% \text{ of } 20 = 0.20 \times 20 = 4 \text{ students}
\]
3. **Remaining students after contemporary dance:**
\[
20 - 4 = 16 \text{ students}
\]
4. **Percentage of the remaining students enrolled in jazz dance:**
\[
25\% \text{ of } 16 = 0.25 \times 16 = 4 \text{ students}
\]
5. **Students enrolled in hip-hop dance:**
\[
16 - 4 = 12 \text{ students}
\]
6. **Percentage of the entire class enrolled in hip-hop dance:**
\[
\frac{12}{20} \times 100\% = 60\%
\]
\[
\boxed{60\%}
\]
