Answer 1

$answer \: > \\ 1. \: \frac{13}{18} + ( \frac{ 5}{ - 12} ) \\ \frac{26 + ( - 15)}{36 } \\ \frac{11}{36 } \\ \\ 2. \: \frac{7}{ - 15} + \frac{ - 2}{3} \\ \frac{ - 7 + ( - 10)}{15} \\ \frac{ - 17}{15} \\ 3. \: \frac{ - 7}{8} - \frac{ - 5}{8} \\ \frac{ - 7 - ( - 5)}{8 } \\ \frac{ - 7}{5} \\ \frac{ - 2}{8} \\ \frac{ - 1}{4} \\ 4. \: \frac{5}{7} \times ( \frac{14}{ - 25}) \times \frac{15}{8} \\ - \frac{70}{175} \times \frac{15}{8} \\ \frac{1050}{1400} \\ \frac{3}{4}$
