Quizplus · Accepted Answer

To add fractions, they must have a common denominator. The least common denominator of 4 and 8 is 8. Convert $\frac{3}{4}$ to $\frac{6}{8}$ so both fractions have the same denominator. Then, $\frac{6}{8} + \left(-\frac{5}{8}\right) = \frac{1}{8}$.

Add - 34+(−58)\frac { 3 } { 4 } + \left( - \frac { 5 } { 8 } \right)43​+(−85​)

Add
- $\frac { 3 } { 4 } + \left( - \frac { 5 } { 8 } \right)$
