Step-by-step explanation:

1. \frac{9}{13} + \frac{6}{13} = \frac{15}{13}

✤ Hence, Denominators are same add directly numerators

  • \frac{9~+~6}{13}

  • \frac{15}{13}

2. \frac{7}{-12} + \frac{5}{-13} = \frac{-151}{156}

  • \frac{-7}{12} + (\frac{-5}{13})

  • - \frac{7}{12} - \frac{5}{13}

✤ LCM of 12 and 13 is 156

  • \frac{ - \: 91 \: - 60}{156}

  • \frac{-151}{156}

3. \frac{ 2 }{ \frac{1}{4} } = 8

  • 2 × \frac{4}{1}

  • 8 ✅
