Answer 1

Answer:

1): (D)

3): (B)

5): (D)

7): (A)

Step-by-step explanation:

$1) \: (- \frac{ 1 }{12}) + \frac{11}{12} + \frac{17}{12} \\ - \frac{ 1 }{12} + \frac{11}{12} + \frac{17}{12} \\ \frac{ - 1 + 11 + 17}{12} \\ = \frac{27}{12} \\ = \frac{9}{4} \\ 3) \: ( - \frac{5}{14} ) + ( - 15) + \frac{11}{14} \\ = - \frac{5}{14} - 15+ \frac{11}{14} \\ = \frac{ - 5 - 210 + 11}{14} \\ = - \frac{ 204}{14} \\ = - \frac{102}{7} \\ 5) \: ( - \frac{1}{6} ) + ( - \frac{1}{6} ) + \frac{5}{6} \\ = - \frac{1}{6} - \frac{1}{6} + \frac{5}{6} \\ = \frac{ - 1 - 1 + 5}{6} \\ = \frac{3}{6} = \frac{1}{2} \\ 7) \: ( - \frac{8}{9} ) + \frac{10}{9} + \frac{10}{9} \\ = - \frac{8}{9} + \frac{10}{9} + \frac{10}{9} \\ = \frac{ - 8 + 10 + 10}{9} \\ = \frac{12}{9} = \frac{4}{3}$
