You can put this solution on YOUR website! When it comes to percents, I go back to the
root of the word " cent " which means one hundred.
So, " per cent " means " per one hundred "
---------------------------------------
If you have any number, usually a fraction, and you
want to express it as ( some number )% , the % sign
means you are dividing by one hundred.
Remember it is " per one hundred '
----------------------------------------------
So, I don't want to change the value of the fraction
that I have, I just want to put a % sign after it.
But to do that, I have to multiply it by 100. Then
what I'm doing to it is multiplying by 100/100
or 100%, which is the exact same thing.
------------------------------------------
Suppose you have  and you want to
express it as a percent. In order not to change it's
value, I must multiply by  or 100%
which is the same thing, so I have:
 %
Note that if I didn't tack on the % sign, I would be
changing the value of the fraction -not allowed!
-------------------------------------------
Now if I tack on the % sign, I have really multiplied
by and I haven't changed a thing
is the same thing as  %
( but only with the % tacked on )
--------------------------------------------
Does this clear it up at all? Let me know
