Answer

1$\frac{7}{9}$.

Work Step by Step

We start by subtracting the whole numbers: $3-1=2$. In order to add or subtract fractions, we start by making a common denominator (bottom of the fraction). Thus, we multiply 2/3 by 3/3 to obtain: $\frac{6}{9}-$($\frac{8}{9}$)$=-\frac{2}{9}$. We add the 2 to get an answer of 1$\frac{7}{9}$.
