To multiply \(\frac{4}{5} \times -9\):

\[ \frac{4}{5} \times -9 = \frac{4 \times -9}{5} = \frac{-36}{5} \]

This can also be expressed as a mixed number. \(-\frac{36}{5}\) is equal to \(-7 \frac{1}{5}\).

Among the provided responses, the correct answer is:

−7 15

(but note that it should actually be written as −7 1/5 for clarity).
