  1. Answer:

    L.H.S. = 3/4 + 7/8 = (6+7) / 8 = 13/8

    R.H.S. = 7/8 + 3/4 = (7+6) / 8 = 13/8

    L.H.S. = R.H.S.

    The property used here is commutative property of addition for rational numbers.

  2. Answer:

    Hey friend,

    Here is the answer you were looking for:

    \begin{gathered} – \frac{3}{4} + \frac{7}{ – 8} = \frac{7}{ – 8} + ( – \frac{3}{4} ) \\ \\ – \frac{3}{4} + ( – \frac{7}{8} ) = – \frac{7}{8} – \frac{3}{4} \\ \\ – \frac{3}{4} – \frac{7}{8} = – \frac{7}{8} – \frac{3}{4} \\ \\ \frac{ – 3 \times 2 – 7 \times 1}{8} = \frac{ – 7 \times 1 – 3 \times 2}{8} \\ \\ \frac{ – 6 – 7}{8} = \frac{ – 7 – 6}{8} \\ \\ = \frac{ – 13}{8} = \frac{ – 13}{8} \end{gathered}
