1. The problem statement, all variables and given/known data If I have a number with an uncertainty and I want to divide it by a number without an uncertainty (ex. if it's just a constant, like pi), what do I do with the uncertainty? Is it ok to just divide the uncertainty by that number? ex. (4.05 +/- 0.3) / 3 Do I divide the 0.3 uncertainty by 3, and that would be my uncertainty for the final answer, or do I have to do percentage uncertainties? 2. Relevant equations N/A 3. The attempt at a solution Intuition tells me it's the first, but I'm not sure.
