-5 $\frac{1}{2}$

Step-by-step explanation:

Change all to improper fractions.

(-2 $\frac{3}{4}$ )×2 = - $\frac{11}{4}$ × $\frac{2}{1}$

- $\frac{11}{4}$ × $\frac{2}{1}$ = - $\frac{22}{4}$

Simplify to mixed numbers.

- $\frac{22}{4}$ = -5 $\frac{2}{4}$

Simplify to simplest form.

-5 $\frac{2}{4}$ = -5 $\frac{1}{2}$
