Ineed again! sorry guys!
it is a word problem by the way.
one fourth of the candy bars are not chocolate. there are 45 chocolate candy bars. one fifth of the chocolate bars contained nuts. how many chocolate bars contained nuts?
i know it sounds like an easy problem but i just want to make sure.
thx!

The only hard part is ignoring that first sentence:  "One fourth of the candy bars are not chocolate."  It sounds so official and so necessary, but it's only there to confuse people who have no clue.

Look at just the rest of the question, without all that stuff at the beginning,
and I'll bet you'll slap yourself upside the head:

-- There are 45 chocolate candy bars.
-- One fifth of the chocolate bars contained nuts.
-- How many chocolate bars contained nuts?

One fifth of 45 . . . . . 45/5 = 9 .

Isn't that sneaky, how they worded that question ? ! ?

And who cares how many bars are not chocolate !
