如何让表格和文字并排显示？

Question

我正在使用这个序言

\documentclass[11pt]{book}
\usepackage[paperheight=9.5in,paperwidth=8in, top=1in, bottom=0.8in, twocolumn]{geometry}
\setlength{\columnseprule}{0.4pt}
\usepackage{amssymb,amsfonts}
\usepackage{mathrsfs}
\usepackage[centertags]{amsmath}
\usepackage{amsthm}
\usepackage{amsmath}
\newtheorem{theorem}{Theorem}
\usepackage{epsfig}
\usepackage{float}


\usepackage{graphicx}\graphicspath{{Graphics/}}
\usepackage{mathptmx}
\usepackage[square,sort&compress]{natbib}
\usepackage{pgf,tikz,pgfplots}
\pgfplotsset{compat=1.15}
\usetikzlibrary{arrows}
\usepackage[T1]{fontenc}
\usepackage{fancyhdr}\pagestyle{fancy}
\usepackage{xcolor}
\usepackage{setspace}
\usepackage{booktabs}

\usepackage{enumitem}
\setlist[enumerate,2]{label=(\roman*).}
\usepackage{tasks}
\settasks{label=$\circ$}
\usepackage{tikz}
\usetikzlibrary{fit, tikzmark}       
\tikzset{FIT/.style = {
        draw=black, thick, inner sep=2pt, rounded corners, fit=#1,
        node contents={}},
    s/.style= {inner xsep=6pt}
}


%\usepackage{hyperref}
\usetikzlibrary{arrows.meta}
\renewcommand{\baselinestretch}{1.5}
\newcommand\aug{\fboxsep=-\fboxrule\!\!\!\fbox{\strut}\!\!\!}
\theoremstyle{definition}

\begin{document}
 \begin{tabular}{|c|c|c|}\hline
    \text{Marks}&\text{Frequency} $f$&\text{Cumulative Frequecny}\\\hline
    \text{0---10}&3&3\\
    \text{10---20}&5&8\\
    \text{20---30}&9&17\\
    \text{30---40}&3&20\\
    \text{40---50}&2&22\\\hline
\end{tabular}\qquad
Location of $Q_1=\dfrac{n}{4}th$ item$=\dfrac{22}{4}th$ item$=5.5$th item\\
Location of $Q_3=\dfrac{3n}{4}th$ item$=3\dfrac{22}{4}th$ item$=16.5$th item
\end{document}

但它就像图片所示

我建议你将tabular环境和方程式都放在table*或figure*环境中。这样，它们就可以并排摆放。
