    Reduce fraction in LaTex

    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.

    Re: Reduce fraction in LaTex

    Hello, TheEmptySet!

    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.
