1

\frac{5}{6}

2

- \frac{5}{6}

3

\frac{6}{5}

4

\frac{- 6}{5}

Explanation:

$\frac{6}{5}$
$(- 2) \div (? ? - \frac{5}{3})$
$= - 2 \times (- \frac{3}{5})$ $x \div y = x \times \frac{1}{y}$
$= \frac{- 2}{1} \times \frac{(- 3)}{5}$
$= \frac{- 2 \times (- 3)}{1 \times 5}$ $(\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d})$
$= \frac{6}{5}$
Hence, the correct answer is option (c).
