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?

Answer 1

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
`30 = [5/6]x` 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.

`30 * [6/5]=36`

Thus, there are 36 words on the list.

Answer 2

36

Explanation:

1. Cross Multiply.
`(5)/(6) =(30)/(x)`

2. Solve.
`(5)/(6) =(30)/(x) =36`

3. Your answer is 36
