Duplicate of How to make sense of fractions? | |
| Mar 25, 2018 at 17:00 | comment | added | Xander Henderson♦ | @ArnaudMortier I am not disputing any of that. I just don't feel that it is terribly relevant in this case, in which a little bit of searching would have found the answer. This is the "research" part of the tooltip which pops up when one chooses to downvote. In the case of this question, I think that it is entirely reasonable to close it as a duplicate. And, just in case you are worried about your reputation, closing a question as a duplicate does not generally lead to deletion, thus your XPs are safe. | |
| Mar 25, 2018 at 16:45 | comment | added | Arnaud Mortier | @XanderHenderson fair enough. But I do think that the OP put great effort into writing that question, and also that it is very helpful to others who may have the same trouble without the ability to put it into words. | |

| Mar 25, 2018 at 15:59 | comment | added | Xander Henderson♦ | @ArnaudMortier Being well posed is not the only reason that one might downvote a question. A lack of research and/or effort is another reason, or the voter may simply feel that the question is not "useful," whatever they think that means. Personally, I think that this question is substantially the same as this one or this one. I am sure that other examples could be found with more than 30 seconds of searching. | |

| Mar 25, 2018 at 1:40 | comment | added | Fattie | you're quite right, @Servaes, but with fractions "that" confusion is more pronounced: with "one third", you "really" want to think of it as one third "of something". | |

| Mar 24, 2018 at 22:34 | comment | added | Servaes | @Fattie This is no more or less fundamental than natural numbers. Most people have no problem with expressions such as "three" without specifying three pies, three houses, three hundred, etc etc. There is however some confusion about how fractions relate to division, or perhaps, as Henry's answer illustrates, the fact that division distributes over addition. | |
| Mar 24, 2018 at 22:23 | comment | added | Fattie | The really fundamental confusion here is this: say I say "a third". It's really only meaningful as a third of something. A third of a pie, a third of a house, a third of one hundred, etc etc. However, by convention, we can just write "one third" (1 over 3) on its own, and in fact by convention that means one third "of one". It's actually very confusing, very stupid, and very strange, but it makes sense once you see it that way and accept it for what it is! | |

| Mar 24, 2018 at 15:47 | comment | added | Arnaud Mortier | The question is pretty well posed, and makes great sense. I don't understand the downvote. | |
