E. $\dfrac{27}{14}$

1. $7$ $\dfrac{2}{4}$ $ - $ $4$ $\dfrac{3}{7}$
$ = \dfrac{30}{4}$ $ - $ $\dfrac{31}{7}$
$ = \dfrac{30\times 7}{4\times 7}- \dfrac{31\times 4}{7\times 4}$
$ = \dfrac{210}{28}-\dfrac{124}{28}$$=\dfrac{{210}-{124}}{28}$$=\dfrac{43}{14}$ $= 3\dfrac{1}{14}$ 2. No More Steps

Correct! Nice work!
