Adding and subtracting Rational numbers

Answer 1

Answer:

$⟹ \frac {3}{5} + \frac {-4}{8} + \frac {7}{5}\\</p><p>\\</p><p>⟹ \frac {3}{5} + \frac {7}{5} -\frac{4}{8}\\</p><p>\\</p><p>⟹\frac {3 + 7}{5} - \frac {4}{8}\\</p><p>\\</p><p>⟹ \frac {10}{5} - \frac {4}{8}\\</p><p>\\</p><p>⟹ 2 - \frac{4}{8}\\</p><p>\\</p><p>⟹ \frac {2}{1} - \frac {4}{8}\\</p><p>\\</p><p>⟹ \frac {16 - 4}{8}\\</p><p>\\</p><p>⟹ \frac {12}{8}\\</p><p>\\</p><p>⟹ \frac {3}{2}$

Answer 2

Answer:

$⟹\frac {3}{5} + \frac {-4}{8} + \frac {7}{5}\\</p><p>\\</p><p>⟹ -\frac {4}{8} + \frac {3}{5} + \frac {7}{5}\\</p><p>\\</p><p>⟹ -\frac{4}{8} + \frac {3 + 7}{5}\\</p><p>\\</p><p>⟹ -\frac {4}{8} + \frac {10}{5}\\</p><p>\\</p><p>⟹ - \frac {1}{2} + \frac {2}{1}\\</p><p>\\</p><p>⟹ \frac {-1 + 4}{2}\\</p><p>\\</p><p>⟹ \frac {3}{2}$
