Solution:
Given:
Converting the numbers into decimal form,
[tex]\begin{gathered} \sqrt{17}=4.12310562562 \\ \\ \frac{34}{7}=4.85714285714 \\ \\ 2.\bar{45}=2.4545454545 \end{gathered}[/tex]
Hence, arranging the numbers in order from the least to greatest,
[tex]2.454545454545,\text{ }4.12310562562,\text{ }4.85714285714[/tex]
Therefore, the correct order is;
[tex]2.\bar{45},\sqrt{17},\frac{34}{7}[/tex]
