Step-by-step explanation:
[tex] = - \frac{5}{9} - ( - \frac{14}{15} )[/tex]
[tex] = - \frac{5}{9} + \frac{14}{15} [/tex]
[tex] = - \frac{5 \times 5}{9 \times 5} + \frac{14 \times 3}{15 \times 3} [/tex]
[tex] = - \frac{25}{45} + \frac{42}{45} [/tex]
[tex] = \frac{ - 25 + 42}{45} [/tex]
[tex] = \frac{42 - 25}{45} [/tex]
[tex] = \frac{17}{45} [/tex]
