Answer 1

$[tex] = ( \frac{7}{5} \times \frac{ - 12}{13} ) + ( \frac{7}{5} \times \frac{5}{12} ) \\ \\ = \frac{7}{5} ( \frac{ - 12}{13} + \frac{5}{12} ) \\ \\ = \frac{7}{5} ( \frac{ - 12 \times 12 + 5 \times 13}{13 \times 12} ) \\ \\ = \frac{7}{5} ( \frac{ - 144 + 65}{13 \times 12}) \\ \\ = \frac{7}{5} ( \frac{ - 79}{13 \times 12} ) \\ \\ = \frac{ - 79 \times 7}{5 \times 13 \times 12} \\ \\ = \frac{ - 553}{780}$
