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$√(28)$&\centering$(23)/(4)$&\centering$5.\overline{5}$&\centering$5(1)/(2)$ \end{tabular} \end{center}`

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


`√(28)\approx5.29 \\ \\ (23)/(4)=5.75 \\ \\ 5.\overline{5}=5.5555 . . . \approx5.56 \\ \\ 5(1)/(2)=5.50`

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


`(23)/(4)\ \textgreater \ 5.\overline{5}\ \textgreater \ 5(1)/(2)\ \textgreater \ √(28)`
