jiani gets paid for a job every 9 weeks and rosa gets paid for a job every 12 weeks. how many weeks will it take for them to get paid at the same time? type your response into the box below.

Answer 1

To find out how many weeks it will take for Jiani and Rosa to get paid at the same time, we need to find the least common multiple (LCM) of 9 and 12.

The prime factors of 9 are 3 * 3.
The prime factors of 12 are 2 * 2 * 3.

To find the LCM, we take the highest power of each prime factor:
2 * 2 * 3 * 3 = 36.

Therefore, it will take them 36 weeks to get paid at the same time.
