If you use backslash \ before the percent % symbol in latex, you will return % symbol as the output.
And this is the easiest way to represent % symbol in a document.
| Symbol | Percent |
|---|---|
| Type of symbol | Operator |
| Package | No |
| Argument | No |
| Latex command | \% |
| Example | A \% B → A % B |
\documentclass{article}
\begin{document}
\[ \frac{2}{5} = 40\% \]
\[ \frac{3}{5} = 60\% \]
\end{document}
Output :
By mistake, you will always try to use the keyboard’s percent symbol indirect text. However, as a result, you will not see any percentage symbol as output.
\documentclass{article}
\begin{document}
% latex percent symbol
$ 0.6 = 60\% $
\end{document}
Output :
Because % symbol in latex is only used to represent single line comment.
Insert percentage symbol in text
In the case of text mode, you need to add \ symbol before % symbol. There is no separate rule for this.
If you use only a percentage(%) symbol in a text, the text on the right side of percentage symbol will be converted to a single-line comment.
\documentclass{article}
\begin{document}
50\% means 50 per 100 \\[4pt]
25% means 25 per 100
\end{document}
Output :
Use siunitx package for value and percentage symbol
In this package, the percent symbol has been considered as SI Unit. As a result, you can print the value and symbol together in the document.
\documentclass{article}
\usepackage{siunitx}
\begin{document}
\[ \qty{75}{\percent} = \frac{75}{100} \]
\[ \qty[color=red]{45}{\percent} = \frac{45}{100} \]
\[ \qty[unit-color=red]{32}{\percent} = \frac{32}{100} \]
\end{document}
Output :
