Answer 3

Calculation of Total Pages in the Book

To find the total number of pages in the book, we can use the information given that Andriy read 24 pages, which is two-thirds (or two-eighths) of the entire book.

Let's denote the total number of pages in the book as 'x'. According to the given information, 24 pages is equal to two-eighths of the total number of pages.

Therefore, we can set up the following equation:

2/8 * x = 24

To solve for 'x', we can multiply both sides of the equation by 8/2:

x = 24 * (8/2)

Simplifying the equation, we get:

x = 96

Therefore, the total number of pages in the book is 96.

Conclusion

Andriy read 24 pages, which is two-eighths of the entire book. Therefore, the total number of pages in the book is 96.
