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 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

    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
