need help simplifying
I'm working on some online homework and I've tried answering this question twice (max 3 tries) and I think I have the right answer now, but I'd like to be sure. Can this be simplified any further? Thanks!

(Wait) If its an online test you are giving than its not allowed in the forum

(Hi)
$\displaystyle \frac{\frac{1}{t+9}}{\frac{1}{t+9} - 4}$

$\displaystyle \frac{\frac{1}{t+9}}{\frac{1-4(t+9)}{t+9}}$

$\displaystyle \frac{1}{1-4t-36}$

$\displaystyle \frac{-1}{4t+35}$

It's open book homework, I assure you. I can screencap if necessary. Thanks so much for your help! I was able to reverse-engineer your math so I could understand it and repeat it myself. Thanks again!
