Find two rational numbers between

Since both the fractions $\left(\frac{-2}{9}\right.$ and $\left.\frac{5}{9}\right)$ have the same denominator, the integers between the numerators $(-2$ and 5$)$ are $-1,0,1,2,3,4$.

Hence, two rational numbers between $\frac{-2}{9}$ and $\frac{5}{9}$ are $\frac{0}{9}$ or 0 and $\frac{1}{9}$.
