Question

Frank needs to memorize words on a vocabulary list for Latin class. He has memorized
6

of the words, which is two-thirds of the list. How many words are on the list?

Answer 1

There are 9 words on the list. If you see that 2/3 x 3/2 = 1, you can multiply 6 by 3/2 to get 9, since this is a proportion problem.
