I think it's $0.20

You just move the period twice to the left.

Example $20 1st/ $2.0 2nd/ $0.20

Hope that helped

$20 x 20%

= $20 x 20/100

= $20 x 1/5

= $20/5

= $4

20% of $20

To get 20% of 20

you multiple 20/100 by 20

so 20(20)/100 = 4

Okay, well you agree that 20% = 20/100, right? and that an unknown value out of $20 could be written as x/20? Great. Set them equal to each other.

20/100 = x/20

Now use cross multiplication.

100x = 20 * 20

100x = 400

x = 4

so, $4 is 20% of $20.

First find how many 20s are in 100 (since there's 20% out of 100%), which is 5, then divide the 20$ by 5, which equals 4.

Simply do the same thing with any other numbers. ;]

$4 is the 20% of $20.

How is it?

One of the easiest way to get the percentage is this:

Change the rate (20%) to decimal. ---> 20% ---> .20

And then, multiply it to the base ($20). ---> .20 x $20

Finally, you've got the answer!

That's how I've got $4.

work out 10% and times it by 2

or... 20% goes into 100% 5 times so divide $20 by 5
