Raina needs to memorize words on a vocabulary list for Russian class. She has memorized 24 of the words, which is three-fourths of the list. How many words are on the list?

Solution

SOLUTION : LET THE TOTAL NO. OF WORDS THAT RAINA HAS TO MEMORIZED IS X.

NOW , SHE HAS MEMORIZED THE WORDS = 24

BUT ACCORDING TO THE QUESTION ( 3 / 4 ) X = 24
