To find out when Jiani and Rosa will get paid at the same time, we need to determine the least common multiple (LCM) of their pay periods: 9 weeks and 12 weeks.

1. **Find the prime factorization of each number:**
- 9: \(3^2\)
- 12: \(2^2 \times 3^1\)

2. **Identify the highest power of each prime:**
- For the prime number 2, the highest power is \(2^2\) (from 12).
- For the prime number 3, the highest power is \(3^2\) (from 9).

3. **Multiply these together to get the LCM:**
\[
LCM = 2^2 \times 3^2 = 4 \times 9 = 36
\]

Thus, Jiani and Rosa will both get paid at the same time in **36 weeks**.
