A. $1\dfrac{19}{30}$ A. $1\dfrac{19}{30}$
B. $\dfrac{5}{11}$
C. $\dfrac{12}{11}$
D. $1$
E. $\dfrac{59}{30}$

1. $6$ $\dfrac{4}{5}$ $ - $ $5$ $\dfrac{1}{6}$
$ = \dfrac{34}{5}$ $ - $ $\dfrac{31}{6}$
$ = \dfrac{34\times 6}{5\times 6}- \dfrac{31\times 5}{6\times 5}$
$ = \dfrac{204}{30}-\dfrac{155}{30}$$=\dfrac{{204}-{155}}{30}$$=\dfrac{49}{30}$ $= 1\dfrac{19}{30}$ 2. No More Steps

Correct! Nice work!
