B. $\dfrac{7}{11}$
C. $\dfrac{12}{11}$

E. $\dfrac{67}{30}$

1. $8$ $\dfrac{2}{5}$ $ - $ $3$ $\dfrac{5}{6}$
$ = \dfrac{42}{5}$ $ - $ $\dfrac{23}{6}$
$ = \dfrac{42\times 6}{5\times 6}- \dfrac{23\times 5}{6\times 5}$
$ = \dfrac{252}{30}-\dfrac{115}{30}$$=\dfrac{{252}-{115}}{30}$$=\dfrac{137}{30}$ $= 4\dfrac{17}{30}$ 2. No More Steps

Correct! Nice work!
