In one case the question is asking how to call the numbers in the range between 0 and 1; in the other case, the question is asking how to call the fractions of 1.
In the first case, I see the question as too broad, because the numbers in the range between 0 and 1 include 0.1, 0.01, 0.0001, 0.333333, 1.25/10, the logarithm with base 10 of 2; those numbers are rational numbers, or irrational numbers, but those terms apply to any real number, not to numbers included in the range between 0, and 1. If the question would have specified that it was asking about 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0,8, 0.9, and 1 it would have been probably different.
In the second case, fractions like 1/8, 1/12000, 1/3, 1/40 doesn't have a specific name, but they are generically called fractions.
The questions have been closed because they cannot be reasonably answered in their current form, which means there isn't a specific word for the question being asked. It is not a real question doesn't mean the user is stating something, instead of asking a question; it means:
- the question is ambiguous, vague, incomplete, overly broad, or rhetorical
- it cannot be answered in its current form
If they were not closed as not a real question, they could have been closed at too localized, as knowing that fractions of 1 are still called fractions doesn't help any future reader.
Re-opening both the questions, and then closing one as duplicate of the other one is not something that I would do because:
- A question that is closed, and that deserves to be closed, is not re-opened to be closed again with a different reason.
- supposing that one of the questions is really asking about 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0,8, 0.9, and 1, then the two questions are not really duplicates.
To notice that the closing reason reported when a question is closed is the one chosen from the majority of the users who voted to close; if 3 users voted to close as not a real question, and 2 users voted to close as too localized, then the question result closed as not a question.
Re-opening the question to close it again could still have the result of having the question closed for the exact same reason because, for example, 4 users vote to close as not a real question, and a users votes to close as not constructive.
