Multiply by 0.21.

hi, depends on if you need to find out 21% of any amount in order to add or substract from the amount:
21% = 0.21
eg: 1 x 21% = 0.21
eg 10 x 0.21 = 2.10
or if you need to find 21% (net) from the total amount (gross). this allows you to find what amount is 21% of a total (which already includes the 21%)
use this if you want 21% has already been added and you want to know what the value of 21% is based on the total given
using the above examples
1 + 0.21 = 1.21
10 + 2.10 =12.10
to find 21% of the totals:
1.21 / (121/100) = 1 or 1.21 / 1.21 = 1
12.1 / (121/100) = 10 or 12.10 /1.21 = 10
hence in both answers 21% would be
1.21-1 = 0.21
12.10 - 10 = 2.10
however if you'd like to find what percentage a total was reduced to:
eg 1.21 is reduced to 1
then 1.21 - 1 = 0.21
0.21 / 1 x 100 = 21%
eg 12.10 is reduced to 10
then 12.10 - 10 = 2.10
2.10 / 10 x 100 = 21%
hope this helps

21 *amount/100

Um, seriously? Take a calculator, take the amount times 21% which will give you the number that you are looking for. IE: 100 x 21% = 21.00 or 50 x 21%= 10.50. Or if you have no calculator, you can take the number times 21 and move the decimal point over to the left two spaces. IE: 100 x 21= 2100 (move decimal point over two to give you 21.

Divide the amount by 100 and then multiply it by 21.

Take the number you have divide it by 100 and then multiply by 21
eg, If you needed to find out 21% of 200, then
200/100 = 2
2x21 = 42
so 21% of 200 = 42

21% is equal to 21/100, so you can multiply the amount by 0.21
I.e
- Amount x 0.21

Take the total amount and multiply it by .21
example: 150 X .21 = 31.5

you can do:
21 (21%) divided by 100 multiplied by the amount you want.

Multiply it by .21

Multiply the amount with 0.21. which means first you divide it with a hundred to find %1 and then multiply it with 21 to reach the desired answer.
by the way I liked to way leets69 did...
