$\bold{Explanation:}$

$\sf= > \dfrac{5}{8} + \dfrac{9}{2} +\bigg ( - \dfrac{4}{5}\bigg ) + \dfrac{7}{8} + \bigg( - 52 \bigg) + \dfrac{7}{5}$

$\sf= > \dfrac{5 + 9 \times 4}{8} - \dfrac{ 4 \times 8 + 7 \times 5}{40} +\dfrac{ 7 }{5}-52$

$\sf= > \dfrac{5 + 36}{8} - \dfrac{32 + 35}{40} + \dfrac{7-52\times5}{5}$

$\sf = > \dfrac{41}{8} - \dfrac{67}{40} - \dfrac{253}{5}$

$\sf= > \dfrac{41 \times 5- 67-253 \times 8 }{40}$

$\sf = > \dfrac{205- 67- 2024}{40}$

$\sf= > \dfrac{138- 2024}{40}$

$\sf= > - \dfrac{1886}{40} = - \dfrac{943}{20}$
