Problem Analysis

We are given a book with 180 pages. On the first day, 2/9 of the book was read, and on the second day, 1/5 of the book was read. We need to determine how many pages are left to be read.

Solution

To find the number of pages left to be read, we need to subtract the number of pages read from the total number of pages in the book.

Let's calculate the number of pages read on the first day: 2/9 * 180 = 40

Now, let's calculate the number of pages read on the second day: 1/5 * 180 = 36

To find the total number of pages read, we add the number of pages read on the first day and the number of pages read on the second day: 40 + 36 = 76

Finally, to find the number of pages left to be read, we subtract the total number of pages read from the total number of pages in the book: 180 - 76 = 104

Therefore, there are 104 pages left to be read.

Answer

There are 104 pages left to be read.
