Ronita moved 1/3 of the books in her backpack to the kitchen table. Three boiks were already on the table. There are 5 books on the table now. How many books,b,were orginally in Ronita's backpack?

Respuesta :

To find the number of books that were in Ronita's book bag originally, you will find how many book were added to the table by subtracting 5 and 3.  She added 2 books.

2 books are 1/3 of her total books.  In math this can be written as: 

1/3x = 2
1/3     1/3
x= 6 books

Ronita had 6 books in her book bag.
