$\frac{5}{3}$
This figure consists of two shapes: one which is divided into thirds but shaded completely, representing 1 whole (the same as $\frac{3}{3}$) and another which has two of its three equal parts shaded, representing $\frac{2}{3}$. In total, $1\frac{2}{3}$ is shaded. To represent the mixed number $1\frac{2}{3}$ as a fraction, simply add $\frac{3}{3}$ and $\frac{2}{3}$ to get $\frac{5}{3}$.
