If you say "That dress is 15% off today !! " I have no idea how to figure it. At all. I've tried. I've been taught. It just doesn't stick. Or if you tell me "A generous tip is 20% of the bill"...I can't figure that.
Which is why my dh ...who has a passion for all things numbers...teaches the children math.
I agree though...that a math teacher should understand the concept before teaching a child.

I was a cocktail waitress. I can do fifteen percent of anything. It's really easy.
All you have to remember is that all numbers can be broken down into chunks of 10%, 5%, and 1%.
Ten percent is the easiest. You move the decimal to the left.
For example: If your restaurant bill comes to $267.44, ten percent of that is what you get when you move Mr. Decimal: $26.744, or (more basically), $26.74.
Some more examples:
Ten percent of $358.33 = $35.833 (or $35.83)
Ten percent of $1,999,786.00 = $19,997,860.00
Once you have ten percent, it's really easy to find one percent. Just move the decimal over one more time to the left.
Ten percent of $358.33 = $35.833 (or $35.83)
One percent of $358.33 = $3.5833 (or $3.58)
Ten percent of $10.00 = $1.00
One percent of $10.00 = .10 cents
Once you have ten percent, it's also easy to find five percent. Just cut your 10% figure in half, because five is half of ten.
Ten percent of $562.24 = $56.224 (or $56.22)
Five percent of $56.22 = $28.11
Ten percent of $10.00 = $1.00
Five percent of $10.00 = .50 cents.
To get fifteen percent  Take ten percent. Cut it in half. Add it to the original ten percent.
Fifteen percent of $10.00 =
Ten percent ($1.00) plus five percent (.50 cents) equals $1.50.
To get other percents (like, let's say, seventeen percent)
Ten percent
PLUS
Five percent
PLUS
One percent
PLUS
One percent.
17% of $10.00 =
Ten percent ($1.00) plus
Five percent (.50 cents) plus
One percent (one cent) plus
One percent (one cent)
=$1.52
Hope that helps. It's much easier than they taught you in school.
