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

Answer:

36

Step-by-step explanation:

1. Cross Multiply. $\frac{5}{6} =\frac{30}{x}$

2. Solve. $\frac{5}{6} =\frac{30}{x} =36$

3. Your answer is 36

Answer 2

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.

$30 \times [6/5]=36$

Thus, there are 36 words on the list.
