Question

Four people have found the perimeter of a forest using different methods. Their results are given in the table . Order their calculations from greatest to least

Answer 1

Given that four people have found the perimeter of a forest using different methods.

Given the table below of their results.

$\begin{center} \begin{tabular} {|p {2cm}|p {2cm}|p {2cm}|p {2cm}|} \multicolumn {4} {|c|} {Distance Across Quarry Canyon}\\[1ex] \centering Juana&\centering Lee Ann&\centering Ryne&Jackson\\[1ex] \centering \sqrt{28} &\centering \frac{23}{4} &\centering 5.\overline{5} &\centering 5\frac{1}{2} \end{tabular} \end{center}$

 To order their calculations from greatest to least, we first convert all the measurements to decimal.

$\sqrt{28}\approx5.29 \\ \\ \frac{23}{4}=5.75 \\ \\ 5.\overline{5}=5.5555 . . . \approx5.56 \\ \\ 5\frac{1}{2}=5.50$

Therefore, the ordering of the measurements from greatest to least is as follows:

$\frac{23}{4}\ \textgreater \ 5.\overline{5}\ \textgreater \ 5\frac{1}{2}\ \textgreater \ \sqrt{28}$
