$\frac{16}{-21}\times\frac{-14}{5}$
✓
Answer
$\frac{16}{-21}\times\frac{-14}{5}$$\frac{16}{-21}=\frac{16\times(-1)}{-21\times(-1)}$
$=\frac{-16}{21}$
$\therefore\frac{-16}{21}\times\frac{14}{5}$
$=\frac{(-16)\times(-14)}{21\times5}$
$=\frac{(-16)\times(-2)}{3\times5}$
$=\frac{32}{15}$
$=\frac{-16}{21}$
$\therefore\frac{-16}{21}\times\frac{14}{5}$
$=\frac{(-16)\times(-14)}{21\times5}$
$=\frac{(-16)\times(-2)}{3\times5}$
$=\frac{32}{15}$
