Step-by-step explanation:
-5 5/16
The multiplication of fractions and mixed numbers can be performed by converting them into improper fractions, multiplying the numerators and denominators, and then simplifying, if necessary. Be mindful of the signs: multiplying two negatives results in a positive, while multiplying a negative and a positive results in a negative. Each step should be followed carefully to ensure the calculations are accurate.
