Answer with explanation:
The numbers which we have to arrange from least to greatest are:
1.→2.717171.......71.....
[tex]2 \rightarrow 2 \frac{3}{4}=\frac{11}{4}\\\\=2.75[/tex]
3. √5=2.2360
[tex]4.\rightarrow \frac{5}{2}=2.5[/tex]
Ascending order of the four numbers are
[tex]\sqrt{5}<\frac{5}{2}<2.717171......<2.75[/tex]
