Answer 2

We will add the following Fractions :-

$(c) \frac{2}{3} + \frac{ - 4}{5} + \frac{ - 2}{3} + 1 + \frac{ - 11}{15} \\ \\ \\ = \frac{10 + - 12 + - 10 + 15 + - 11}{15} \\ \\ \\ = \frac{ - 12 + 15 - 11}{15} \\ \\ \\ = \frac{15 - 23}{15} \\ \\ \\ = \boxed{ \frac{ - 8}{15} }$

$(a) \frac{ - 13}{20} + \frac{11}{14} + \frac{ - 5}{7} + 1 \\ \\ \\ = \frac{ - 91 + 110 + - 100 + 140}{140} \\ \\ \\ = \frac{250 - 191}{140} \\ \\ \\ = \boxed{\frac{59}{140} }$
