We start by converting 10% to a fraction :
10% = 1/10
Then we have
10% of 20 = 1/10 x 20 = 1/10 x 20/1 = 20/10
Notice that 20 was rewritten as the fraction 20/1, and that to multiply two fractions together, you simply multiply the numerators and denominators.
In order to find the simplest form of the fraction 20/10 we cancel out the greatest common divisor of 20 and 10, which is 10 :
20/10 = 2/1
So the final answer is
10% of 20 = 2
Method 2
Alternately, we can convert 10% directly to a decimal :
10% = 0.1
Then, doing the calculation by hand or with a calculator, we find
10% of 20 = 0.1 x 20 = 2
So the final answer is
10% of 20 = 2

The answer is 2. I will show you why
take .1*20
the point .1 is the decimal from of 10% then you get 2
to check your work you can take 2/20 and then you should get .1 then times that by 100 and you get 10 so then you can say that 10% of 20 is 2.

First: make the percentage a decimal (place a decimal after the 2nd digit - move the decimal 2 places to the left).
10% ==> 0.10
Sec: multiply the decimal with the whole number.
(0.10)(20) = 2

is/of = %/100
what is means x
10%
of 20
x/20=10/100
This is the same as (x/20)=.1
x=(.1)(20)=2
