@ColinTheMathmo what are mixed numbers ? 😅

@Turambar From the emoji I assume that's a joke, but from some people it would be a genuine question. Some people really don't know.

So consider 2⅛ ... or in \( \LaTeX \) ...

\( 2\frac{1}{8} \)

Some people don't know that it's 17/8 (\(\LaTeX\) : \(\frac{17}{8}\))

When decomposing fractions in real part/fractional part in elementary school, we wrote it 2 + ⅛

@Turambar In England (and Australia) "Mixed Numbers" are a very real thing -- you learn about them early. If you talk about "Two and a half cakes" then you write "2½ cakes" ... the juxtaposition of numbers is, by convention, taken to mean addition.

Similarly, you you write "vingt trois" in digits you write "23", and that doesn't mean "2 times 3".

We have conventions, and the purpose of the original toot is to point out that conventions vary across countries.

In England, 8¾ has the value 8.75.
