Hey guys, I got this problem on my math sheet and I have no idea if I did it right because it's the first time I see something with a division and two multiplications.

Thanks,
EE

2. $\frac{a}{b} \div \frac{c}{d} \ne \frac{b}{a} \times \frac{c}{d}
$

$\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}
$

3. That's what I thought after I finished.. Thanks

4. Do I have to flip the last two? Or just the middle one? I am now confused

you only "flip" for division ... just the middle one.

6. Hey, thanks for the reply. I did that yesterday and I think I got it right.

7. The answer you put is incorrect. It is the reciprocal of that.

$$\frac{(2w-3)(2w+3)^2}{6}$$

You can test any simplification or expansion/contraction problem by assigning the variable an arbitrary value, then solve for the original equation and then your result.
