I simplified it with 5, where it is 5*6=30 and 5*73=365. Those two numbers are only divisible by 5. So, I just simplified it with 5. Please open the image and check how I did it. If you 12/30*365, you get 146.
Please let me know if you need any clarification. I'm always happy to answer your questions.
