$$| \frac { - 27 } { 25 } \div \frac { 3 } { 5 } | \times | \frac { - 15 } { 64 } \times \frac { - 16 } { 5 } |$$
$\frac{27}{20}=1.35$
$$|\frac{-27\times 5}{25\times 3}||\frac{-15}{64}\times \frac{-16}{5}|$$
$$|\frac{-9}{5}||\frac{-15}{64}\times \frac{-16}{5}|$$
$$|-\frac{9}{5}||\frac{-15}{64}\times \frac{-16}{5}|$$
$$\frac{9}{5}|\frac{-15}{64}\times \frac{-16}{5}|$$
$$\frac{9}{5}|-\frac{15}{64}\times \frac{-16}{5}|$$
$$\frac{9}{5}|-\frac{15}{64}\left(-\frac{16}{5}\right)|$$
$$\frac{9}{5}|\frac{-15\left(-16\right)}{64\times 5}|$$
$$\frac{9}{5}|\frac{240}{320}|$$
$$\frac{9}{5}|\frac{3}{4}|$$
$$\frac{9}{5}\times \frac{3}{4}$$
$$\frac{9\times 3}{5\times 4}$$
$$\frac{27}{20}$$
