Long equation, and the equation number, does not fit into 1 column!

Question

I have a 2 columns LaTeX document (in overleaf). I want to add a formula in one of the columns.

My current code looks like this:

\[0.39\frac{total\_word\_count}{total\_sentence\_count} + 
11.8\frac{total\_syllable\_count}{total\_word\_count}\tag{1}\]

And produces the following equation (in the right column, which is where I want it):

I showed some text above and below to give an impression of how it looks in the text.

Ideally I want it to look like:

EQUATION (1)

short description

I tried using the \begin{equation} field with resizebox, but did not succeed.

Any help would be appreciated!

Answer 1

By use of the \mfrac instruction defined in the nccmath package:

\documentclass[twocolumn]{article}
\usepackage{nccmath}

\usepackage{lipsum}

\begin{document}
\lipsum[1][1-3]
\begin{equation}
0.39\mfrac{\textrm{total\_word\_count}}{\textrm{total\_sentence\_count}} {+}
11.8\mfrac{\textrm{total\_syllable\_count}}{\textrm{total\_word\_count}}
\end{equation}
\lipsum[1][4-5]
\end{document}

Answer 2

Various possibilities:

\documentclass[twocolumn]{article}

\usepackage{amsmath}

\begin{document}

dont use math italic (or number by hand)
\begin{equation}
0.39\frac{total\_word\_count}{total\_sentence\_count} + 
11.8\frac{total\_syllable\_count}{total\_word\_count}
\end{equation}



scriptstyle
\begin{equation}\scriptstyle
0.39\tfrac{\textrm{total\_word\_count}}{\textrm{total\_sentence\_count}} {+} 
11.8\tfrac{\textrm{total\_syllable\_count}}{\textrm{total\_word\_count}}
\end{equation}

two lines
\begin{multline}
0.39\frac{\textrm{total\_word\_count}}{\textrm{total\_sentence\_count}} \\
+ 11.8\frac{\textrm{total\_syllable\_count}}{\textrm{total\_word\_count}}
\end{multline}

shorter names
\begin{equation}
0.39\frac{\textrm{tword}}{\textrm{tsentence}} + 
11.8\frac{\textrm{tsyllable}}{\textrm{tword}}
\end{equation}


\end{document}
