SUMMARY
When dividing a number with uncertainty by a constant without uncertainty, the uncertainty should be divided by that constant. For example, dividing (4.05 +/- 0.3) by 3 results in a final value of 1.35 with an uncertainty of 0.1. This method maintains the integrity of the uncertainty calculation, confirming that the uncertainty is scaled appropriately when performing division. The correct approach is to apply the same operation to the uncertainty as is applied to the value itself.
