Question 1 Report

$\frac{\frac{2}{3} \div \frac{4}{5}}{\frac{1}{4} + \frac{3}{5} - \frac{1}{3}}$

\frac{31}{50}

\frac{20}{31}

\frac{31}{20}

\frac{50}{31}

Answer Details

$\frac{\frac{2}{3} \div \frac{4}{5}}{\frac{1}{4} + \frac{3}{5} - \frac{1}{3}}$
$\frac{2}{3} \div \frac{4}{5} = \frac{2}{3} \times \frac{5}{4}$
= $\frac{5}{6}$
$\frac{1}{4} + \frac{3}{5} - \frac{1}{3} = \frac{15 + 36 - 20}{60}$
= $\frac{31}{60}$
$∴ \frac{\frac{2}{3} \div \frac{4}{5}}{\frac{1}{4} + \frac{3}{5} - \frac{1}{3}} = \frac{5}{6} \div \frac{31}{60}$
= $\frac{5}{6} \times \frac{60}{31}$
= $\frac{50}{31}$
