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

2
because 10% is one-tenth
also dividing by 10
so 20/10 = 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.

10%=1/10

1/10* 20/1=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

%means 100
10% of 20 means 10/100*20=20*10/100=200/100=2
ans 2

Ten percent of 20 is 2.

You get this by multiplying 0.1 by 20.

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
