Re: Percentages

If you have one cake and divide between people they get half each - this is fractions.  2 x 1/2 = 1 (two halfs equal one whole).  Another way to look at it is to say they get 50% each because just as 1/1 is a whole cake, 100% is also the whole cake.  Since 50 is half of one hundred and they each get half of the cake, they are receiving 50% of the cake each.
   You can also look at it as 1/2 (one divided by two) = 0.5!   1.00 is the whole cake and 0.50 is half of it i.e. 50%.
   Go to www.google.com and have a look for GCSE mathematics material and I'm sure you will come up trumps.

P.S. GCSE is the british exams that all state school children take at around 16 years of age.

Do you understand fractions?
If you do, then I think this will help you:

Re: Percentages

find 1% of 20 i.e. divide it by 100.
20/100 = 0.2 (20 pence)    ==    1% of 20
now multiply this by 8 to find 8%.

Re: Percentages

First figure out what 1% is by dividing by 100.

20 ÷ 100 = 20p.

Then multiply by the percentage.

20p x 8 = 160p = 1.60.


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

Re: Percentages

They both did it by going to 1% first, but you can also just turn 8% into a fraction.
Just put 8/100 (simplified as 2/25) and you will find out that fraction is equal to .08
Multiply .08 by 20 to get 1.6

Or you could simply move the decimal point... 8% is technically 8.0%, and if you want to convert that to a decimal, move the decimal point to spaces to the left, making it .08, and multiply that by 20 to get 1.6.

Other examples of moving the decimal point are 50% is equal to 50.0% move it 2 to the left and you get .5... .5 is equal to 1/2 and half of 20 is 10, so 50% of 20 would be 10.

Re: Percentages

Or you can multiply 20 by 0.08.
