Answer :
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.
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.
