The easiest way to know the smallest and highest number is to convert the fractions to decimal. Therefore,
[tex]\begin{gathered} -\frac{1}{2}=-0.5 \\ \frac{7}{12}=0.58333333333 \\ -\frac{2}{3}=-0.66666666666 \\ -0.45 \\ 0.82 \\ \text{The least to greatest is } \\ -\frac{2}{3},-\frac{1}{2},-0.45,\frac{7}{12},0.82 \end{gathered}[/tex]
