# What is 20% of \$20 ?

and if you could explain how you got to the answer, i've never learned well about percentages and we'll start using them a lot in my algebra + trigonometry class.

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 Of 20

\$20 x 20%

= \$20 x 20/100

= \$20 x 1/5

= \$20/5

= \$4

\$4. 20% = 1/5 and 1/5 of 20 = 4

20% of \$20

To get 20% of 20

you multiple 20/100 by 20

so 20(20)/100 = 4

10% of 20 would be 2

10% + 10% or 2 + 2=\$4

20% = .2

x = .2 * 20

x = 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

That's how I've got \$4.
