B. $\dfrac{5}{11}$
C. $\dfrac{12}{11}$

E. $\dfrac{35}{18}$

1. $9$ $\dfrac{1}{2}$ $ - $ $6$ $\dfrac{4}{9}$
$ = \dfrac{19}{2}$ $ - $ $\dfrac{58}{9}$
$ = \dfrac{19\times 9}{2\times 9}- \dfrac{58\times 2}{9\times 2}$
$ = \dfrac{171}{18}-\dfrac{116}{18}$$=\dfrac{{171}-{116}}{18}$$=\dfrac{55}{18}$ $= 3\dfrac{1}{18}$ 2. No More Steps

Correct! Nice work!
