Respuesta:

$(3 - 0.4) - ( \frac{7}{15} \times \frac{3}{28} + \frac{9}{4} ) = \\ (3 - \frac{4}{10} ) - ( \frac{1}{20} + \frac{9}{4} ) = \\ (3 - \frac{2}{5} ) - ( \frac{1}{20} + \frac{9}{4} ) = \\ ( \frac{15}{5} - \frac{2}{5} ) - ( \frac{1}{20} + \frac{45}{20} ) = \\ \frac{13}{5} - \frac{46}{20} = \\ \frac{52}{20} - \frac{46}{20} = \\ \frac{6}{20} = \\ \frac{3}{10}$
