E. $\dfrac{37}{15}$

1. $4$ $\dfrac{4}{6}$ $ - $ $2$ $\dfrac{4}{5}$
$ = \dfrac{28}{6}$ $ - $ $\dfrac{14}{5}$
$ = \dfrac{28\times 5}{6\times 5}- \dfrac{14\times 6}{5\times 6}$
$ = \dfrac{140}{30}-\dfrac{84}{30}$$=\dfrac{{140}-{84}}{30}$$=\dfrac{28}{15}$ $= 1\dfrac{13}{15}$ 2. No More Steps

Correct! Nice work!
