Math question
When trying to find the price per item it always confused me which is the numerator and which is the denominator?
While we're at it what's a dividend?
Ok so I buy bulk tobacco, 500 cigarettes worth for $32
Dividing
500 by 32 we get .064
That's how much a cigarette costs me
Is .1 a tenth of a cent?
.06 being a hundredth
And .004 being a thousandth?
------
So it costs me how much? Don't we have to round up to the nearest whole number sorta cause we can't have fractions of a cent?
Eeek if I wanted to cell a penny worth of cigarettes how much would it be?
.64rths of a penny?

If it's price per item, you divide by the number of items (just like you get mol/L by dividing a number of moles by the number of litres).
$32/500 cigs = 0.064 $/cig, or 6.4 cents/cig. A penny's worth of a cig would be 1/6.4 or 0.15 cigarettes.
Please remember: "Filtrate" is not a verb.

So if we are talking chemistry here we have a conversion factor that is pretty much 500 cigarettes / 32 $ that reads for every 500 cigarettes we have,
there are 32 dollars. With the conversion factor you can flip it and apply it in a number of ways.
.1 is a tenth of anything, depending on the units, which is the most important part of the .1, as it describes what. In the event of 0.064, which is
what you got per cigarette, there is no .1, so there is no "tenth" of a cent, however, there is a 0.06 which is a hundredth of dollar, since dollars
were the units used in the Denominator (the lower part) of the conversion factor, being the 32 $. and 6 hundredths of a dollar is 6 cents.
