1) Order the numbers below from least to greatest.

\(\Large \frac{5}{12} \hspace{5mm} \frac{3}{8} \hspace{5mm} \frac{1}{7} \hspace{5mm} \frac{1}{2} \hspace{5mm} \frac{7}{9} \hspace{5mm}\)\(0.25 \hspace{5mm} 0.333\)

Order:  \(\Large\frac{1}{7}\hspace{5mm}0.25\hspace{5mm}0.333\hspace{5mm}\frac{3}{8}\hspace{5mm}\frac{5}{12}\hspace{5mm}\frac{1}{2}\hspace{5mm}\frac{7}{9}\)

2) How can you be sure you have the correct order? Use pictures, diagrams, and other strategies to explain your thinking.
