A student recorded the exact percentage frequency distribution for a set of measurements, as shown below. However, the student neglected to indicate N, the total number of measurements. What is the smallest possible value of N?
\begin{tabular}{c c}
\text{measured value} & \text{percent frequency} \\
\hline
0 & 12.5 \\
1 & 0\\
2 & 50\\
3 & 25 \\
4 & 12.5 \\ \hline
\ & 100 \\
\end{tabular}
