The table shows the frequency distribution of pizza sizes. Determine the percentage of the medium pizzas. 

\begin{array}{|c|c|c|}
\hline \text { Pizza Choice } & \text { Number } & \% \\
\hline \text { Small } & 51 & \\
\hline \text { Medium } & 76 & \\
\hline \text { Large } & 33 & \\
\hline \text { Total } & & 100 \\
\hline
\end{array}

\(47.5\% \)

\(\begin{align}
&\text { Total number }=160 \\
&\begin{aligned}
\therefore \text { Medium Pizza's} &=\frac{76}{160} \times 100 \% \\
&=47.5 \%
\end{aligned}
\end{align}\)
\begin{array}{|c|c|c|}
\hline \textbf { Pizza Choice } & \textbf { Number } & \mathbf{\%} \\
\hline \textbf { Small } & 51 & 31.9 \\
\hline \textbf { Medium } & 76 & 47.5 \\
\hline \textbf { Large } & 33 & 20.6 \\
\hline \textbf { Total } & \mathbf{160} & \mathbf{100}\\
\hline
\end{array}
