To calculate \( \frac{35}{8} + 8 \), first convert 8 into a fraction with a common denominator:
\[ 8 = \frac{8 \times 8}{1 \times 8} = \frac{64}{8} \]
Now, add the two fractions:
\[ \frac{35}{8} + \frac{64}{8} = \frac{35 + 64}{8} = \frac{99}{8} \]
So, \( \frac{35}{8} + 8 = \frac{99}{8} \) or you can also express it as a mixed number:
\[ \frac{99}{8} = 12 \frac{3}{8} \]
Therefore, the answer is \( \frac{99}{8} \) or \( 12 \frac{3}{8} \).
