8 8/13 + 6 5/13 =

Add the whole numbers and the fractions separately:

Whole numbers: \( 8 + 6 = 14 \)

Fractions: \( \frac{8}{13} + \frac{5}{13} = \frac{8 + 5}{13} = \frac{13}{13} \)

Combine the whole number and the fraction:

\( 14 + \frac{13}{13} \)

Since \( \frac{13}{13} = 1 \), we have:

\( 14 + 1 = 15 \)
