Step 1.1

Move the leading negative in $- \frac{2}{3}$ into the numerator.

$\frac{- 2}{3} \cdot ((- 9 y) (\frac{3}{2})) \cdot (8 x) \cdot 0$

Step 1.2

Factor $3$ out of $(- 9 y) (\frac{3}{2})$ .

$\frac{- 2}{3} \cdot (3 (- 3 y \frac{3}{2})) \cdot (8 x) \cdot 0$

Step 1.3

Cancel the common factor.

$\frac{- 2}{3} \cdot (3 (- 3 y \frac{3}{2})) \cdot (8 x) \cdot 0$

Step 1.4

Rewrite the expression.

$- 2 \cdot (- 3 y \frac{3}{2}) \cdot (8 x) \cdot 0$

Step 2

Combine $- 3$ and $\frac{3}{2}$ .

$- 2 \cdot (y \frac{- 3 \cdot 3}{2}) \cdot (8 x) \cdot 0$

Step 3

Multiply $- 3$ by $3$ .

$- 2 \cdot (y \frac{- 9}{2}) \cdot (8 x) \cdot 0$

Step 4

Combine $y$ and $\frac{- 9}{2}$ .

$- 2 \cdot \frac{y \cdot - 9}{2} \cdot (8 x) \cdot 0$

Step 5

Combine $- 2$ and $\frac{y \cdot - 9}{2}$ .

$\frac{- 2 (y \cdot - 9)}{2} \cdot (8 x) \cdot 0$
