Answer 1

$\frac{7}{4} \frac{7}{4} \div ( \frac{4}{3} - \frac{2}{8})( \frac{4}{3} \frac{2}{8} ) \times3$

$\frac{49}{16} \div \frac{2}{5} \times \frac{2}{5} \times 3 \\ \frac{49}{16} \div \frac{2}{5} \times \frac{5}{16} \\ \frac{49}{16} \div \frac{12}{75} = 4 \frac{1}{2}$

$\frac{5}{3} \frac{5}{3} - ( \frac{2}{5} \times \frac{7}{2} )( \frac{2}{5} \times \frac{7}{2} ) - \frac{1}{3} \frac{1}{3}$

$\frac{25}{9} - \frac{14}{10}\frac{14}{10} - \frac{1}{9} \\ \frac{25}{9} - \frac{196}{100} - \frac{1}{9} = \frac{ - 172}{ - 100}$

$\frac{5}{3} \frac{5}{3} - ( \frac{2}{5} \times \frac{7}{2} - \frac{1}{3} )( \frac{2}{5} \times \frac{7}{2} - \frac{1}{3} )$

$\frac{25}{9} - \frac{13}{7} \frac{13}{7} \\ \frac{25}{9} - \frac{169}{49} = \frac{ - 169}{ - 40}$
