I think it is important for one to be able to follow instructions even if they might appear counterintuitive. The rule for conversion is to divide by 100. It doesn't matter what percentage I give you; always divide by 100. It's fairly straightforward but many people are unable to do so in the case of 0.25%. They expect the answer to be 25.
