Answer 1

2 / 9 x (9 / 4 x - 9) = ?
/ means divide

Answer 2

Answer:

$\frac{8\cdot x}{81 - 324\cdot x}$

Step-by-step explanation:

The expression is:

$\frac{2}{9\cdot (\frac{9}{4\cdot x}-9)}$

$\frac{2}{9\cdot (\frac{9-36\cdot x}{4\cdot x} )}$

$\frac{2}{9}\cdot \frac{4\cdot x}{9-36\cdot x}$

$\frac{8\cdot x}{81 - 324\cdot x}$
