$\tt \: \frac{8}{27} \: + \: \frac{ - 9}{54}$

$\mathtt\pink{L.C.M\:=\:54}$

$\tt = \frac{8 \: \times \: 2}{27 \: \times \: 2} \: + \: \frac{( - 9) \: \times \: 1}{54 \: \times \: 1} \\ \\ \tt = \: \frac{16}{54} \: + \: \frac{( - 9)}{54} \\ \\ \tt = \: \frac{16 \: + \: ( - 9)}{54} \\ \\ \tt = \: \frac{16 \: - \: 9}{54}$
