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

We know that 30 is 5/6 of the list. So we can find out how many words are on the list with the following equation:



Solve for x by isolating it. First we multiply both sides by 6 to cancel out the one-sixth.



Next divide both sides by 5 to cancel out the 5 being multiplied to the x.



The answer is 36 words.

The list has 36 words

Explanation:
Assume that the number of words on the list is x.
We are given that:
5/6 of the number of words on the list is equal to 30 words.
This means that:
(5/6)*x = 30
Solve for x as follows:
(5/6)*x = 30

5x = 6*30
5x = 180
x = 180/5
x = 36

Hope this helps :)
