Answer:

The union of A and B is the set of all those elements which belong either to A or to B or both A and B. Now we will use the notation A U B (which is read as 'A union B') to denote the union of set A and set B. Thus, A U B = {x : x ∈ A or x ∈ B}.

Answer:

-12

Step-by-step explanation:

Convert the mixed number to an improper fraction.

-2 $\frac{2}{3}$ = $-\frac{8}{3}$

To divide, just multiply by the reciprocal.

So -2 $\frac{2}{3}$ ÷ $\frac{2}{9}$ becomes $-\frac{8}{3}$ ÷

Now you can multiply straight across.

$-\frac{8}{3}$ × $\frac{9}{2}$ = $-\frac{72}{6}$

And simplify.

$-\frac{72}{6}$ = -12
