B. $\dfrac{6}{13}$
C. $\dfrac{14}{13}$

E. $\dfrac{79}{42}$

1. $6$ $\dfrac{1}{6}$ $ - $ $4$ $\dfrac{5}{7}$
$ = \dfrac{37}{6}$ $ - $ $\dfrac{33}{7}$
$ = \dfrac{37\times 7}{6\times 7}- \dfrac{33\times 6}{7\times 6}$
$ = \dfrac{259}{42}-\dfrac{198}{42}$$=\dfrac{{259}-{198}}{42}$$=\dfrac{61}{42}$ $= 1\dfrac{19}{42}$ 2. No More Steps

Correct! Nice work!
