Quizplus · Accepted Answer

To add or subtract fractions, they must have a common denominator. The least common denominator (LCD) of 2 and 9 is 18. Convert each fraction to an equivalent fraction with a denominator of 18: $-\frac{1}{2} = -\frac{9}{18}$ and $-\frac{4}{9} = -\frac{8}{18}$. Adding these gives $-\frac{9}{18} - \frac{8}{18} = -\frac{17}{18}$, which is in lowest terms.
