8/c*d/14

To simplify the expression \( \frac{8}{c} \cdot \frac{d}{14} \), you can multiply the numerators together and the denominators together:

\[ \frac{8 \cdot d}{c \cdot 14} \]

This simplifies to:

\[ \frac{8d}{14c} \]

Next, you can simplify the fraction \( \frac{8}{14} \):

\[ \frac{8}{14} = \frac{4}{7} \]

So, the final simplified expression is:

\[ \frac{4d}{7c} \]
