We have 4 numbers and we have to sort them from greatest to least.
![\begin{gathered} 0.49 \\ 78\%=0.78 \\ (3)/(7)=0.\bar{428571}\text{ (periodic)} \\ (7)/(15)=0.4\bar{6} \end{gathered}](https://img.qammunity.org/qa-images/2023/formulas/mathematics/college/8m2fzsjikn3z0jpm704g.png)
If we ordered them we have: 0.78, 0.49, 0.46..., 0.428471...
This corresponds to Athena, Christian, Alexis, Lokyn.
Other way to solve it would have been to look for the common denominator for all this numbers, and then compare the numerators.
