converting mixed number to improper fraction?
Did someone remove the info about converting a mixed number to improper fraction? I have trouble finding the info about it.Joeleoj123 (talk) 14:35, 4 March 2018 (UTC)
Putting my question here because it seems related. Under "Simple, common, or vulgar fractions" it reads "Compound fractions, complex fractions, mixed numerals, and decimals (see below) are not simple fractions..." but under 'Complex' and 'Compound' fractions," the last step of the first example simplifies from the improper fraction 3/2 to the mixed number 1 1/2. Should that not stop at 3/2? Clussman (talk) 19:32, 5 July 2019 (UTC)
Good point. Fixed. Rick Norwood (talk) 12:56, 6 July 2019 (UTC)
'Positive or negative, proper, or improper'
@Deacon Vorbis: You reverted my removal of the comma following 'proper' in the above quote (citing MOS:STYLERET); I assume this is because you believed I was removing an Oxford comma. I wasn't: this is not three items in a series and is not a matter of American vs. British convention. 'Positive or negative' and 'proper or improper' are two sets of opposing descriptors for fractions, and it is correct to set them off with a comma, as I have corrected it to (i.e. 'positive or negative, proper or improper'). Another possibility, I suppose, is to forgo commas altogether: 'positive or negative and proper or improper'; personally I think the former sounds better (and is easier to parse).
The way that the quote was and is again punctuated misleadingly (and erroneously) regroups the terms: (positive) or (negative, proper, or improper). (I concede that there exists a third possibility which may be preferable if one is insistent on having a series, 'positive, negative, proper(,) or improper'; however, this no longer expresses the opposition of positive vs. negative and proper vs. improper and may in fact suggest all four as competing options (though of course readers well versed in fractions would not be misled).)
I hope I have explained my point clearly. Cheers. Coreydragon (talk) 18:08, 6 May 2019 (UTC)
- @Coreydragon: That's fair; I went ahead with kind of a hybrid: "...can be positive or negative, and they can be proper or improper". Hopefully that works without being too awkward. –Deacon Vorbis (carbon • videos) 19:33, 6 May 2019 (UTC)
- @Deacon Vorbis: Thanks for your understanding. While it might be a bit wordy, I think there's no room for confusion in your version, so maybe that's best. Works well enough for me, at least. Cheers. —Coreydragon (talk) 19:52, 6 May 2019 (UTC)

- Support. It should be noted that the two other mathematical items of the dab pages are subtopics and do not really need to be disambiguated. In particular, Algebraic fraction is the "main article" of a section of the same name in Fraction (mathematics). D.Lazard (talk) 07:11, 22 June 2020 (UTC)

Simple vs Vulgar
I could have sworn that as a kid (50ish years ago) I was taught that a simple fraction was a 1 over a 4 with a horizontal "mathematically proper" form line, and the vulgarized version was with a slash. The concept was that the slash was an "everyday man" convenience notation, while the Simple was a mathematic definition.
The "Vulgar" attribute was literally meant as "an afront to the proper", or words to that effect.
Just a musing on the subject; I understand that this is not a forum. Was there a change in history at some point, or was this simply an error on my part?

- The original meaning of "vulgar" is common. The common Latin Bible is called the "Vulgate" Bible. Those who started using the word "vulgar" to mean dirty obviously had a low opinion of the common people.

"Top" and "bottom"
The Monty Hall Problem by Jason Rosenhouse, p. 43, says (as an aside):
|“||(Among mathematicians, incidentally, it is commonplace to refer to the top and bottom of a fraction. Jawbreakers like "numerator" and "denominator" figure far more prominently in middle-school mathematics classes than they do in actual mathematical practice.)||”|
Also, in the current body of the article, the terms "top" and "bottom" are used in several places to refer to the numerator and denominator. Should this be explained properly as an informal terminology? (Not sure if this book is an appropriate source, though.)
Or is this usage obvious to native English speakers?
As a non-native speaker, I was unaware of the existence of this informal terms when I read this article on the English Wikipedia. A mention of this would be useful.--22.214.171.124 (talk) 06:45, 23 March 2022 (UTC)
- As a mathematician, I use "numerator" and "denominator" routinely. They are hardly jawbreakers. And while, in a class of beginning college students, I may use "top" and "bottom" informally, they should not replace "numerator" and "denominator" any more than "five-sided thing" and "six-sided thing" should replace "pentagon" and "hexagon". Rick Norwood (talk) 11:52, 23 March 2022 (UTC)
- For fractions, top and bottom are not equivalent to numerator and denominator. Top and bottom refer to places in a specific representation of fractions (syntactic meaning), while numerator and denominator refer to the meaning (semantics) of the numbers or other objects that are at these places. In particular, top and bottom are meaningless for fractions represented as while a and b remain the numerator and the denominator. The difference of meaning is illustrated by a sentence such as: In the fraction the top number (3) is called the numerator and the bottom number (2) is called the denominator.
