Answer 2

L . C . M of

$- 4 \: and \: \: 8 = 8 \\ \frac{27}{ - 4} = \frac{27 \times 2}{( - 4) \times 2} = \frac{54}{ - 8 } \\ \frac{ - 15}{8} = \frac{( - 15) \times 1}{8 \times 1} = \frac{ - 15}{8 } \\ \\ hence \: \frac{27}{ - 4} + \frac{ - 15}{8} = \frac{54}{ - 8 } + \frac{ - 15}{8} \\ = \frac{54 + ( - 15)}{ - 8} = \frac{ - 69}{8}$
