Answer:
[tex]p1 \: \frac{73}{20} \: \: and \: p2 \: - 2 \frac{17}{20} [/tex]
Step-by-step explanation:
[tex]1. \: \frac{7}{5} - ( \frac{ - 9}{4} ) \\ 2. \: \frac{7}{5} + \frac{9}{5} \\ 3. \: \frac{73}{20} \\ \\ \\ 1. \: lcd = 20 \\ 2. \: \frac{2 \times 4}{5 \times 4} - \frac{13 \times 5}{4 \times 5} \\ 3. \: \frac{8}{20} - \frac{65}{20} \\ 4. \: \frac{8 - 65}{20} \\ 5. \: \frac{ - 57}{20} \\ 6. \: - 2 \frac{17}{20} [/tex]
