You have already read 117 pages of a book. You are one third of the way through the book. Write and solve and equation to find the number of pages in the book.

If you have read 117 pages of a book and it's one third of the book, then:

117 = 1/3 x              / * 3 (both sides)
x = 351

So the book has 351 pages overall.
I think u would do 117 x 3 because that is one third of the book and if u did 117 x 3 and the divided the product by 3 u would get 117.
