Quizplus · Accepted Answer

First, find a common denominator for the fractions within the parentheses, which is 35. Convert the fractions and subtract: $\frac{20}{35} - \frac{7}{35} = \frac{13}{35}$. Then, add $\frac{1}{2}$ to the result, converting $\frac{1}{2}$ to $\frac{35}{70}$ to match the denominator, resulting in $\frac{13}{35} + \frac{35}{70} = \frac{26}{70} + \frac{35}{70} = \frac{61}{70}$.
