We all likely know that percent = something over 100, that is x/100.

Did you also know that in a word problem involving percentages, the following conversions can be made:

is...to...=

of, times product...to...* (multiplication symbol)

what...to...any varibable (example "x," "k," "s," "b, or "f")

So when a problem says 38 is what percent of 78, it is saying 38= ?/100 (78)
