To multiply two fractions, you multiply the numerators together and the denominators together.
Given the fractions: \(-\frac{1}{3}\) and \(-\frac{5}{8}\),
Step 1: Multiply the numerators: \[ (-1) \times (-5) = 5 \]
Step 2: Multiply the denominators: \[ 3 \times 8 = 24 \]
Step 3: Combine the results: \[ \frac{5}{24} \]
So, the final answer is \(\frac{5}{24}\).
The correct response from the options given is: 5 over 24.
