Question

3/8 +(-5)/7=21+(-40)/56= -19/56​

Answer 1

Answer:

$⟹\frac{3}{8} + \frac {-5}{7} = \frac{21}{1} + \frac{-40}{56} = \frac{-19}{56}\\</p><p>\\</p><p>⟹\frac {21 - 40}{56} = \frac {1176 - 40}{56} = \frac{-19}{56}\\</p><p>\\</p><p>⟹\frac{-19}{56} = \frac{1136}{56} = \frac {-19}{56}\\</p><p>\\</p><p>⟹ \frac {1136}{56} = \frac{-19}{56} + \frac {19}{56}\\</p><p>\\</p><p>⟹\frac{1136}{56} = \frac {-19 + 19}{56}\\</p><p>\\</p><p>⟹\frac {1136}{56} = \frac {0}{56}\\</p><p>\\</p><p>⟹\frac{1136}{56} = 0$

Answer 2

Answer:

$↦\frac {3}{8} + \frac {-5}{7} = \frac {21}{1} + \frac {-40}{56} = \frac {-19}{56}\\</p><p>\\</p><p>↦ \frac {21 - 40}{56} = \frac {1176 - 40}{56} = \frac {-19}{56}\\</p><p>\\</p><p>↦\frac {-19}{56} = \frac {1136}{56} = \frac {-19}{56}\\</p><p>\\</p><p>↦\frac {1136}{56} = \frac {-19}{56} + \frac {19}{56}\\</p><p>\\</p><p>↦\frac {1136}{56} = 0$
