In my physics class when the tutor talks a value of something, they say that will be "one over something", I'm not sure what this is and I cannot ask because it seems like everyone else knows what he is talking about. I think he's talking about a reciprocal, but I'm not sure why a reciprocal is used.
Ok, so this has been a while but I think I understand what the context of the question was, when the tutor was referring to "one over something", I think he was trying to explain that the value he was discussing would be a fraction of the whole. - Does this make sense?
..I'm not sure which answer to mark as the best as they both have good points.
and thanks for moving this to the maths section.
