Assistance request + Mah brain math is broken.

If I have a pdf that printed at 100% gives an output of 1/3 size - how much do I have to reduce the percentage to print the same thing at 1/4 size?

Thankyou in advance.

[No jokes ta, this is a real math question that is causing me headaches .. ]

I’ve created a collection of handy LaTeX macros that simplify typesetting fractions.

These macros include common fractions, like `\half`, \third, etc. They use "1" as the numerator by default, but you can change it via an optional argument. For example, `\quarter[\pi]` creates π4.

Each macro also has:
- A display version (e.g., `\dhalf`, `\dthird`\)
- A short (e.g., `\halfshort`, which is rendered as 1/2.
​
The short versions make it easy to switch between 12 and 1/2, and, also, the slash scales with the size of the numerator.

I find these macros super useful, so I hope you do, too! The macros and further descriptions are available here:

I’ve also shared some tips for writing with fractions effectively here:

Questions, comments, or suggestions? I’d love to hear them—let me know!


Paul Wintz · FractionsThis collection of LaTeX macros make it easier to insert fractions, including defining a \fracshort macro that causes a fraction to be rendered like $a/b$ (making it easier to switch between $\frac{a}{b}$ and $a/b$). The slash inserted by \fracshort scales with the height of the numerator and denominator. Also included are common fractions, $\frac{1}{2}$ (\half), $\frac{1}{3}$ (\third), etc. Each of these commands can take one optional argument that sets the numerator to the given values, such as \half[x] ($\frac{x}{2}$), and have short versions (\quartershort[\theta] creates $\theta/4$) and a display style version (e.g., \dtenth[n] creates $\dfrac{n}{10}$, but you should never use display style fractions in a line of text). Finally, the \oneover, \oneovershort, and \doneover macros inserts fractions with $1$ in the numerator and the denominator given as an argument: \oneover{x} creates $\frac{1}{x}$. <p> When using the short fractions, make sure you insert parentheses, as needed, around the numerator and denominator!

The Third-of-a-Pound Burger flop

"Ah, fractions. Who needs 'em? Not burger devotees. According to Canadian news outlet CBC, the famous McDonald's Quarter Pounder burger once had a larger cousin, the Third-of-a-Pound Burger...."

That's why it's a bad idea to argue online.

Bonjour à tous ! 👋

Je suis content de partager un travail finalisé et latexisé de mes supports sur les fractions en #6e ! 📚 😀
Toutes les activités sont maintenant disponibles en pdf et LaTeX. 😊🔢

NB : Les activités sont plutôt conçues comme une passerelle vers la compréhension des nombres décimaux. 📈🔟

Activité concernant les fractions, les nombres décimaux avec un axe gradué appliqués au 50 mètres nage libre des JO de Paris 2024.
Première page d'exercices sur les fractions (6e) : - des figures géométriquee découpées et colorées - un dialogue avec des personnages en bas à gauche
Première page de la fiche leçon sur les fractions. Texte à trous et figures géométriques découpées en parts égales.
Image illustrant la façon de placer la fraction 7/4 sur un axe gradué. L'axe montre les positions de 1/4 et 7/4, avec une série de cercles colorés représentant les intervalles. Une personne explique le processus en quatre étapes : repérer les graduations qui divisent une unité en 4 parts égales, compter 7 intervalles à partir de 0, ou alternativement 3 intervalles à partir de 1 (en notant que 7/4 = 1 + 3/4).

Dear @echo_pbreyer, dear @piratenpartei@piratenpartei.social

I want to #vote for a party (and list members) at the #EU #elections that is most effective in influencing EU policies towards #privacy friendliness and #antisurveilance.

#Fractions in the #EUparlament are powerful institutions to gian access to committees and (inside-)information and to influence #EUpolicy.
What fraction are you currently part of/will your successors be part of?

I just managed to write a #Python programme to convert between the #Phugpa Tibetan #calendar and Julian Days, which means the Phugpa calendar can now be converted to and from any other calendar (that I have coded so far).

This ended up being later than I expected, and the Python is really freaking slow, but at least it works. I might need to completely rewrite it in #Fortran at some point, which will be tricky because Fortran doesn't support #fractions. Maybe #Rust does?
