-5 5/6

Explanation:

So the same thing as the last question I answered, we have to multiply the top row and the bottom row. However, the fractions in the photo are actually mixed numbers so we first have to make them into improper fractions.

1 and 2/3 would be: 5/3

-3 and 1/2 would be: - 7/2

So now we have to multiply them:  5/3  * - 7/2:

Same steps: 5 * 7 = 35; 3 * 2 = 6:

- 35/6, or we could simplify and make it a mixed number so and also add the negative sign:

6 goes into 35 5 times so: -5 and 5/6 or -5 5/6
