Deon needs to memorize words on a vocabulary list for Korean class. He has memorized 30 of the words, which is two-thirds of the list. How many words are on the list?
45 words. This must be the case because if we use the equation a=pw then we find that our new equation is 30=\(\frac{2}{3}\)•w. We then find what w, or whole, is equal to and divide a by p. The answer is then 45.
