\frac{39}{28}

\frac{84}{13}

Answer Details

$\frac{1}{3} \div [\frac{5}{7} (\frac{9}{10} - 1 + \frac{3}{4})]$
$\frac{1}{3} \div [\frac{5}{7} (\frac{9}{10} - \frac{10}{10} + \frac{3}{4})]$
= $\frac{1}{3} \div [\frac{5}{7} (\frac{- 1}{10} + \frac{3}{4})]$
= $\frac{1}{3} \div [\frac{5}{7} (\frac{- 2 + 15}{20})]$
= $\frac{1}{3} \div [\frac{5}{7} \times \frac{13}{20}]$
$\frac{1}{3} + [\frac{13}{28}]$ = $\frac{1}{3} \times \frac{28}{13}$
= $\frac{28}{39}$
