$- \frac{22}{9}$ $-22/9$

First, rewrite the mixed number as a fraction.

$- 2 \frac{3}{4}$ $-2 3/4$

$\frac{- 2 \cdot 4 - 3}{4}$ $(-2 * 4 -3)/4$

$\frac{- 8 - 3}{4}$ $(-8-3)/4$

$- \frac{11}{4}$ $-11/4$

Now, rewrite the equation:

$- \frac{11}{4}$ $-11/4$ x $\frac{8}{9}$ $8/9$

Now, we cross-simplify:

$-11/cancel4 xx cancel8/9$

$-11/1 xx 2/9$

$-22/9$

How do you simplify -2 3/4 * 8/9−234⋅89-2 3/4 * 8/9?
