Answer 1

[tex] [\frac{3}{4} *(- \frac{3}{4} )]* \frac{4}{7} + \frac{1}{4} =- \frac{9}{16} * \frac{4}{7} + \frac{1}{4} \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~=- \frac{9}{28} + \frac{1}{4} \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~=- \frac{9}{28} + \frac{7}{28} \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~=- \frac{2}{28} \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~=- \frac{1}{14} [/tex]
