I am trying to receive this look of fractions enter image description here



I need the red numbers, which are over the fractions.
*They need to be normal, not handwritten-like.
Here is my code



documentclass[10pt,oneside,a5paper]{article}

usepackage{amsmath}

begin{document}

    $dfrac{13}{25}, dfrac{9}{20}, dfrac{3}{4},

    dfrac{3}{4}, dfrac{3}{5}, dfrac{1}{6};$

end{document}

  • Do they also have to be printed in such a handwritten-like font?

  • 1




    @R.. there is indeed a risk here as I should probably not have the fracm globally defined to use the xintiiQuo{simeonlcm}{#2} operation. In this approach the fracm should arguably be a macro whose usage is strictly restricted to inside fractionswithlcm argument...

For the curved symbol you can use smile:



documentclass{article}

usepackage{amsmath}



newcommand{fractionswithlcm}[2]{%

  {underbrace{#1}_{displaystyle#2}}%

}

newcommand{fracm}[3]{%

  overset{#1}{overset{displaystylesmile}{frac{#2}{#3}}}%

}



begin{document}



[

fractionswithlcm{

  fracm{12}{13}{25},

  fracm{15}{9}{20},

  fracm{75}{3}{4},

  fracm{60}{3}{5},

  fracm{50}{1}{6}

}{300}

]



end{document}

    With widehat instead of curves:



    mew



    documentclass{article}
    
usepackage{amsmath}
    
begin{document}
    
$overset{underbrace{
    
underset{widehat{dfrac{13}{25},}}{12}

    • But I think that the mark should be below the top numbers, not above the 2nd row numbers.
      – Sigur
      Dec 8 at 16:03










    • It should be curved up, like half circle.
      – Sigur
      Dec 8 at 18:00










    • I think they should be under and centered with the 1st row numbers. Lets see.

    • BTW not relevant to the TeX part, but in this answer 3/5 and 1/6 are switched relative to the question (while the numbers above are not).

      @R.. there is indeed a risk here as I should probably not have the fracm globally defined to use the xintiiQuo{simeonlcm}{#2} operation. In this approach the fracm should arguably be a macro whose usage is strictly restricted to inside fractionswithlcm argument...

    • Amazing. Can you remove the big bracket with number 300. I need only the fractions with the curves.
