To multiply \( 4 \) by \( -\frac{5}{8} \):
\[ 4 \times -\frac{5}{8} = \frac{4 \times -5}{8} = \frac{-20}{8} \]
Next, we simplify \(\frac{-20}{8}\):
\[ \frac{-20}{8} = \frac{-20 \div 4}{8 \div 4} = \frac{-5}{2} \]
This is already in simplest form. Since \(-\frac{5}{2}\) is an improper fraction, we can convert it to a mixed number:
\[ -\frac{5}{2} = -2 \frac{1}{2} \]
So the final answer is:
\(-2 \frac{1}{2}\)
Thus, the correct response is:
−2 1/2
