Whenever you see %, that always means that whatever number is before it should be divided by 100.

So, 6% is 6/100 = 0.06

To find 6% of 2000, just do 0.06 x 2000 = 120.

Why did the vector cross the road?
It wanted to be normal.

Re: please help me :(

6% = 6/100  = .06

Just multiply this by the number you want the percentage of.

2000(.06) = 120

Re: please help me :(

thanks you 2, i really apreciate that, hope your both around 2morrow lol

oh yeh btw, so if for example say 12% of 2000 would that be 0.12x2000=240? ive just tryed it out and thts the answer, so if its a single number you would have to put 0.01 or 2 ect... and if its 2 numbers it would have to be 0.12 or 0.13 ect?

That's right. If it's a single number, just treat it as if it's 02, 03 etc. to make sure you don't get confused. It would be horrible to lose easy marks in a test just because of a silly mistake.

You can do all of the above without a calculator.  It's just multiplying decimals.  Ugly, but it works.

Re: please help me :(

If you want to find x% of y, then it's very easy to do without a calculator as long as y ends in 00, as it does here. Just divide by 100, then multiply by x.

e.g. 6% of 2000.
Divide by 100 to get 20, then multiply by 6 to get 120.
