B. $\dfrac{8}{17}$
C. $\dfrac{18}{17}$
D. $1$
E. $\dfrac{27}{14}$

1. $5$ $\dfrac{3}{7}$ $ - $ $1$ $\dfrac{5}{10}$
$ = \dfrac{38}{7}$ $ - $ $\dfrac{15}{10}$
$ = \dfrac{38\times 10}{7\times 10}- \dfrac{15\times 7}{10\times 7}$
$ = \dfrac{380}{70}-\dfrac{105}{70}$$=\dfrac{{380}-{105}}{70}$$=\dfrac{55}{14}$ $= 3\dfrac{13}{14}$ 2. No More Steps

Correct! Nice work!
