Answer:
The answer will be -45/4 or -11 1/4
Explanation:
The first thing you will do is convert both numbers into improper fractions. -4 1/2 will be -9/2 and 2 1/2 will be 5/2. Once you do that, you will multiply each fraction and you should get -45/4. Finally, you would convert that into a mixed number which would be -11 1/4.
