How tot type fractures, like: ½, ¼ en ¾

Loewie · Post by **Loewie** » Tue Oct 02, 2012 3:13 pm

my pupil on the primary school, works in a PDF-mathbook. (Visually impaired, so she can enlarge the text)
Is there an easy way tot type fractures (like 1/2, 1/4, 3/4, etc. , but then this way: ½, ¼ en ¾ )?

I know it is possible with CTRL+SHIFT+"Num PLUS", or "NUM SUB" , but that is not easy!!!

Hello Loewie,

Actually Using Ctrl-Shift-NumPlus/NumMinus will put your selected text in super/sub script.

The correct way to input 1/4, 1/2 and 3/4 is to hold down the Alt key and then to input the following numbers with the NumPad keys:

Alt-0188 - ¼
Alt-0189 - ½
Alt-0190 - ¾

Best,
Stefan

And is this the way for all other fractures?
3/8, 7/16. 2/9, etc, etc?
Is there a list of combinations (ALT + ....) ?

Hi Loewie

I believe there is only a few fractions available as discrete characters. If you type charmap into a run dialog in Windows you will get a mapping of available Alts. Click a character and below is the Alt code if there is one.

Something to remember here is that because these are characters they are affected by the font used. If a font doesn't have a character for a particular Alt code it will obviously not render.

I suspect that the Maths PDF program your pupil is using will be very limited as to the fractions it can type. You should teach her to type out the fractions as 1/3 3/4 etc. It will be much simpler.

Most fonts will have the common fractions ½ ¼ and ¾, and Times New Roman also contains the fractions ⅓ ⅔ ⅛ ⅜ ⅝ ⅞. Palatino Linotype includes the full range of fractions supported by Unicode, including the less common fractions ⅕ ⅖ ⅗ ⅘ ⅙ ⅚.

Serif™ PagePlus X6 has a Fractions feature, which will automatically format fractions with super/subscripts for numerators and denominators, My OpenType fonts have fraction features that will do the same, but again you are limited to using applications that support OpenType like PagePlus, Word 2010, or InDesign.

Thanks Bhikkhu,

I am in awe of your knowledge of fonts, if not a little jealous...

I think the font Calibri also has the full range of fractions that you are looking for. You can access them using Charmap in Windows.

Thanks for that Arnold,

I see ⅓, ⅔, ⅕, ⅖, ⅗, ⅘, ⅙, ⅚, ⅛, ⅜, ⅝ and ⅞ in Calibri - definitely useful.

Okay, that's clear to me.
Thanks for your help!

Because of all the fractions , she'll have to type it like you suggest: 7/8, etc...

Is there a common rule if you have to make sums like:

6/8 + 7/8 = 1 5/8. A space between 1 and 5/8 is hard to see, when you are visualy impaired.
It look's like 15/8 !!!!

You will have to talk to other teachers about that. I think its beyond the scope of this forum.

I was able to create a PDF test document in PagePlus using OpenType fractions, but unfortunately the OpenType features only work in text, not in form fields. So, you could easily format the question neatly, but typing the answers isn't so neat.

She could perhaps be asked to type the answers in the form — 1 and 5/8
