E. $\dfrac{41}{30}$

1. $8$ $\dfrac{1}{5}$ $ - $ $\dfrac{1}{6}$
$ = \dfrac{41}{5}$ $ - $ $\dfrac{1}{6}$
$ = \dfrac{41\times 6}{5\times 6}- \dfrac{1\times 5}{6\times 5}$
$ = \dfrac{246}{30}-\dfrac{5}{30}$$=\dfrac{{246}-{5}}{30}$$=\dfrac{241}{30}$ $= 8\dfrac{1}{30}$ 2. No More Steps

Correct! Nice work!
