$$\frac{7}{9}\times\frac{-9}{18}+\frac{2}{3}$$
$\frac{5}{18}\approx 0.277777778$
$$\frac{7}{9}\left(-\frac{1}{2}\right)+\frac{2}{3}$$
$$\frac{7\left(-1\right)}{9\times 2}+\frac{2}{3}$$
$$\frac{-7}{18}+\frac{2}{3}$$
$$-\frac{7}{18}+\frac{2}{3}$$
$$-\frac{7}{18}+\frac{12}{18}$$
$$\frac{-7+12}{18}$$
$$\frac{5}{18}$$
