Divided and fractions mean the same thing.
Fractions= numerator divided by denominator.

New one.

Just checking if you can do this and I don't give a shit if you think I suck because I just learnt it then but.

Questions like;

6a+1=5.2. a=?

9.6=1.2-7c. c=?

I had to try this for like 2 hours...Show full workings plz

After that,

-2a(3a+5b-1) is?

the first one...u do like 5.2-1...then divid by 6......which is 4.2 d by 6=0.7...so its easy...(no offence but did u really just learnt that)(and took u 2 hours)?

Subject: Re: Maths questions Mon Oct 26, 2009 9:00 am

Lol..It was like at 11:00...What year did you learn that?

It took me ages because I just wanted to do the sums and I ended up having to go back and reading HOW to do it...Lol

the second one...same thing..do 9.6+1.2=10.8 then divided by 7...then u get the answer -1.54...

Posts : 78 Join date : 2009-09-18

u basicly just do the opposite thing...u get it?

Subject: Re: Maths questions Mon Oct 26, 2009 9:23 am

2nd one is wrong lol.

9.6=1.2-7x.

9.6-1.2=8.4

8.4- -7x=

x=-1.2... Lol

And do the last one as well.

Posts : 78 Join date : 2009-09-18

no..u got it wrong..it saids 9.6=1.2-7xso if its 1.2..7X1.2=8.4..then 1.2 -8.4 is -72 or something...
