Question

Ravi needs to memorize words on a vocabulary list for Russian class. He has memorized 12 of the words, which is two-thirdsof the list. How many words are on the list?

Answer 1

The number of words in the list we'll call it 'x'

We can write this problem as a equation:

`(2)/(3)x=12`

To find the total number of words on the list we clear 'x':

`2x=12*3`
`x=(12*3)/(2)`
`x=18`

The list has a total of 18 words.
