no.

3. yrelhan4 Group Title

nah you cant do that.. you statement basically means.. 1800n/n + 180w/n..

4. burhan101 Group Title

ohh okay

5. yrelhan4 Group Title

1800*

6. burhan101 Group Title

thanks :)

7. yrelhan4 Group Title

Cheers. :)

8. Jhannybean Group Title

The way you wrote it seems a little off. $\large \frac{1800n}{n} + \frac{1800w}{n} = 1800 + \frac{1800w}{n}$

can i multiply h by both terms to get rid of the fraction?

10. Jhannybean Group Title

oh that's an h? lol.

11. burhan101 Group Title

n*

12. yrelhan4 Group Title

You can do that, yes.. but then you have to divide it too to negate that effect. that wont be of any help though as it would result in the same expression as you have right now..

13. burhan101 Group Title

right .. so there's no way to get rid of that n ?

14. primeralph Group Title

Nope. Unless you use an eraser.

I would just divide each part in the numerator by the denominator and see what can cancel out.
