Explicação passo-a-passo:

$( - \frac{1}{3} ) - ( + \frac{2}{4} ) + ( - \frac{3}{7} ) = \\ \\ - \frac{1}{3} - \frac{1}{2} - \frac{3}{7} = \\ \\ - \frac{2}{6} - \frac{3}{6} - \frac{3}{7} = \\ \\ \frac{ - 2 - 3}{6} - \frac{3}{7} = \\ \\ - \frac{5}{6} - \frac{3}{7} = \\ \\ - \frac{35}{42} - \frac{18}{42} = \\ \\ \frac{ - 35 - 18}{42} = \\ \\ - \frac{53}{42} ou \: - 1.262$
