Sean finish reading a 240 page book in three days. On the first day he read 1/3 of the book. On the second day, he read 96 pages. What fraction of the book did she read on the third day?

Sean read a total of 240 pages in the book.

On the first day, Sean read 1/3 of the book, which is (1/3)*240 = 80 pages.

On the second day, he read 96 pages.

Therefore, on the first and second day, Sean read a total of 80 + 96 = 176 pages.

To calculate how many pages Sean read on the third day, we subtract the total pages read so far from the total number of pages in the book: 240 - 176 = 64 pages.

Therefore, Sean read 64 pages on the third day.

To find out the fraction of the book read on the third day, we divide the pages read on the third day (64) by the total pages in the book (240): 64/240 = 4/15.

Therefore, Sean read 4/15 of the book on the third day.
