If she reads at a rate of 18 pages per day, how many days will it take her to read 13
1
3
of the book?

Answer 1

Answer: 4 days

Explanation:

The complete exercise is "Irene is going to read a 216-page book. If she reads at a rate of 18 pages per day, how many days will it take her to read
`(1)/(3)` of the book?"

For this problem you can calculate how many pages
`(1)/(3)` of the book represents.

According to the information given in the exercise, you know that total number of pages the book has is the following:

`total=216`

Therefore, knowing that, you need to multiply that total pages by
`(1)/(3)` . So you get that:

`(1)/(3)(216\ pages)= 72\ pages`

Now, let "x" represents the number of days that will take Irene to read 72 pages.

Knowing that Irene reads the book at a rate of 18 pages per day, you can set up the following proportion:

`(1)/(18)=(x)/(72)`

Finally, you have to solve for "x" in order to find its value. You get that this is:

`(72)((1)/(18))=x\\\\(72)/(18)=x\\\\x=4`

Therefore, it will take her 4 days to read
`(1)/(3)` of the book.
