Resolviendo el primer paréntesis, [tex]1-\frac{3}{5}[/tex] convirtiendo: [tex]=\frac{1\cdot \:5}{5}-\frac{3}{5}[/tex] conservamos el denominador: [tex]=\frac{1\cdot \:5-3}{5}[/tex] [tex]=\frac{2}{5}[/tex]
Calculando el segundo paréntesis [tex]\frac{1}{5}-4[/tex] convirtiendo: [tex]-\frac{4\cdot \:5}{5}+\frac{1}{5}[/tex] conservamos el denominador ya que son iguales [tex]\frac{-4\cdot \:5+1}{5}=-\frac{19}{5}[/tex]
