The problem is asking for the product, meaning we need to multiply.

-2 1/4 * 2 1/2

To make multiplying easier, we can convert the mixed numbers into improper fractions.

2 * 4 = 8, + 1 = 9/4

2 * 2 = 4, + 1 = 5/2

Now, we have this:

-9/4 * 5/2

Since the denominators are different, we can find the least common multiple of the denominators to make them the same. In this case, the least common multiple of 4 and 2 is 4.

-9/4 * 1 = -9/4

5/2 * 2 = 10/4

Now, we have this:

-9/4 * 10/4

We can now multiply!

-9 * 10 = -90

/4 * /4 = /16

= -90/16

You can simply the improper fraction if you'd like.

-90 / 16 = -5.625

So, our answer is -90/16, or -5.625.
