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?

    @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}
    $overset{underbrace{
    underset{widehat{dfrac{13}{25},}}{12}
    underset{widehat{dfrac{9}{20}},}{15}
    underset{widehat{dfrac{3}{4}}, }{75}
    underset{widehat{dfrac{1}{6}}, }{60}
    underset{widehat{dfrac{3}{5}} }{50}
    }}{300}$
    end{document}


    Edit: Ok, with curves



    mwe



    documentclass{article}
    usepackage{amsmath}

    • 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).

    What about this?

    usepackage{amsmath}
    newcommand{myfrac}[3]{overset{#1}{dfrac{#2}{#3}}}

      @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...

            documentclass[10pt,oneside,a5paper]{article}
            usepackage{amsmath}
            newcommand{myfrac}[3]{overset{#1}{dfrac{#2}{#3}}}

            begin{document}
            $myfrac{12}{13}{25}, myfrac{15}{9}{20}, myfrac{75}{3}{4}, myfrac{60}{3}{5}, myfrac{50}{1}{6}$
            end{document}
