Answer 1

To multiply 4 by \(-\frac{5}{8}\):

1. First, multiply the whole number (4) by the numerator of the fraction (-5):
\[
4 \times -5 = -20
\]

2. Then, keep the denominator (8) the same:
\[
\frac{-20}{8}
\]

3. Now simplify \(\frac{-20}{8}\):
\[
\frac{-20 \div 4}{8 \div 4} = \frac{-5}{2}
\]

4. To convert \(-\frac{5}{2}\) to a mixed number, note that \(-\frac{5}{2}\) can be expressed as \(-2 \frac{1}{2}\) since \(-5\) divided by \(2\) is \(-2\) with a remainder of \(-1\).

Thus, the final answer as a mixed number in simplest form is:
\[
\text{−2 } \frac{1}{2}
\]

So the correct response is:
\(-2 \frac{1}{2}\)
