Same denominators — add the numerators and keep the denominator.

• \( \frac{6}{8} + \frac{4}{8} = \frac{6+4}{8} = \frac{10}{8} \)
• \( \frac{10}{8} = \frac{5}{4} = 1\frac{1}{4} \)
• None of the given options (2/8, 3/8, 1/8, 10/16) equals 10/8.

Final Answer: \( \frac{10}{8} \) (none of the listed options match)
