1/( $\frac{1}{24}$ -$\frac{5}{16}$ ):$\frac{-3}{8}$ +1
= $\frac{-13}{48}$ : $\frac{-3}{8}$ +1
= $\frac{-13}{48}$ . $\frac{8}{-3}$ +1
= $\frac{13}{18}$ +1
= $\frac{31}{18}$
2/$\frac{3}{2}$ .3$\frac{5}{6}$ -$\frac{3}{2}$ .2$\frac{1}{6}$
= $\frac{3}{2}$.$\frac{23}{6}$-$\frac{3}{2}$.$\frac{13}{6}$
= $\frac{23}{4}$-$\frac{13}{4}$
= $\frac{5}{2}$
