Quizplus · Accepted Answer

To add fractions with different denominators, first find a common denominator. The least common denominator (LCD) of 7 and 3 is 21. Convert each fraction: $\frac{6}{7} = \frac{18}{21}$ and $\left(-\frac{1}{3}\right) = \left(-\frac{7}{21}\right)$. Adding these gives $\frac{18}{21} + \left(-\frac{7}{21}\right) = \frac{11}{21}$.

Add
- $\frac { 6 } { 7 } + \left( - \frac { 1 } { 3 } \right)$
