Keiko needs to memorize words on a vocabulary list for korean class. she has memorized 30 of the words, which is five-sixths of the list. how many words are on the list?

If 30 words is five-sixths of the list, then six-fifths of 30 should be the whole list (this can be proven by writing the equation and solving for x)

We're going to multiply 30 by the inverse of 5/6 (which is 6/5) to get the total number of words in the list.

Thus, there are 36 words on the list.
