Quizplus · Accepted Answer

To add or subtract fractions, they must have a common denominator. The least common multiple of 9, 3, and 6 is 18. Convert each fraction: $\frac{2}{9} = \frac{4}{18}$, $\frac{2}{3} = \frac{12}{18}$, $\frac{1}{6} = \frac{3}{18}$. Adding and subtracting these gives $\frac{4}{18} + \frac{12}{18} - \frac{3}{18} = \frac{13}{18}$.
