Re: Reduce fraction in LaTex

Hello, TheEmptySet!

Quote:

So I know how to reduce simple fractions is Latex with

\frac{3x}{3y}=\frac{\not{3}x}{\not{3}y}

$\displaystyle \frac{3x}{3y}=\frac{\not{3}x}{\not{3}y}=\frac{x}{y }$

But if I try with a binomial it only crosses out the parenthesis.

$\displaystyle \frac{3\not{(a+b)}}{\not{(a+b)}}=3$

Any ideas would be awesome.

I see that \cancel{ } doesn't work at this site.

The command **\rlap{////}** superimposes //// over the next expression.

\rlap{/////}x+y . . . $\displaystyle \rlap{/////}x+y$

\frac{3(\rlap{////}a+b)}{\rlap{////}a+b} = 3 . . . $\displaystyle \frac{3(\rlap{////}a+b)}{\rlap{////}a+b} =3$

\rlap{////}\backslash\backslash\backslash\backslash . . . $\displaystyle \rlap{////}\backslash\backslash\backslash \backslash$

\rlap{ooo}|||||| . . . $\displaystyle \rlap{ooo}|||||| $

Some symbols can't be used. .You need to experiment.
