$$2 - \frac { 2 } { 3 } \times \frac { 9 } { 16 } \times \frac { 4 } { 27 }$$
$\frac{35}{18}\approx 1.944444444$
$$2-\frac{2\times 9}{3\times 16}\times \frac{4}{27}$$
$$2-\frac{18}{48}\times \frac{4}{27}$$
$$2-\frac{3}{8}\times \frac{4}{27}$$
$$2-\frac{3\times 4}{8\times 27}$$
$$2-\frac{12}{216}$$
$$2-\frac{1}{18}$$
$$\frac{36}{18}-\frac{1}{18}$$
$$\frac{36-1}{18}$$
$$\frac{35}{18}$$
