640 acres / 1 mi^2
7.5 mi^2 (640 acres / 1 mi^2)
= 4,800 acres
note I arranged the conversion factor so it had acres on the top and mi^2 on the bottom
If I wanted to go the other way, from acres to mi^2 I would do it upside down. It is the same top and bottom (640 acres = 1 mi^s)
so all it changes is the language :)
Just do it so the units you do not want cancel. mi^2 * (anythings/mi^2) = anythings
