Answer 2

$\sf\huge\bold{Solution}$

$\sf \longmapsto\bigg[\dfrac{27}{8} - \dfrac{3}{2} -\bigg ( - \dfrac{5}{11} \bigg)\bigg]$

$\sf \longmapsto \dfrac{27}{8} - \dfrac{3}{2} + \dfrac{5}{11}$

=>>LCM of 8,2 & 11 is 88

$\sf \longmapsto \dfrac{27 \times 11 - 3 \times 44 + 5 \times 8}{88}$

$\sf \longmapsto \dfrac{297 - 132 + 40}{88}$

$\sf \longmapsto \dfrac{165 + 40}{88} = \dfrac{205}{88}$

Solving second question:

$\sf \longmapsto\bigg( \dfrac{1}{2} \times \dfrac{8}{3}\bigg ) + \bigg[\dfrac{4}{5} \times - \dfrac{25}{3} \bigg]$

$\sf \longmapsto \dfrac{8}{6} + \bigg[ \dfrac{4}{5} \times - \dfrac{25}{3} \bigg]$

$\sf \longmapsto \dfrac{8}{6} + \bigg[- \dfrac{100}{15} \bigg]$

$\sf \longmapsto \dfrac{8}{6} - \dfrac{20}{3} = \dfrac{8 - 40}{6} = - \dfrac{32}{6} = - \dfrac{16}{3}$
