Let's solve the expression:

\[
\frac{8}{7} - \frac{3}{14}
\]

To subtract these fractions, we need a common denominator. The least common denominator (LCD) of 7 and 14 is 14.

1. Convert \(\frac{8}{7}\) to a fraction with a denominator of 14:

\[
\frac{8}{7} = \frac{8 \times 2}{7 \times 2} = \frac{16}{14}
\]

2. Now subtract \(\frac{3}{14}\) from \(\frac{16}{14}\):

\[
\frac{16}{14} - \frac{3}{14} = \frac{16 - 3}{14} = \frac{13}{14}
\]

So, the answer is:

\[
\frac{13}{14}
\]
