Answer 3

Calculating Remaining Pages to Read

To calculate the remaining pages of the book that Sergey needs to read, we can use the fact that he has read two-ninths of the book in one day.

Let's calculate the remaining pages.

Calculation:

Sergey read two-ninths of the book in one day.

Let's assume the total number of pages in the book is represented by P.

The number of pages Sergey read is given by: 2/9 * P

The number of pages remaining to be read is given by: P - (2/9 * P)

Result:

The number of pages remaining for Sergey to read is 7/9 * P.

Therefore, Sergey has 7/9 of the book left to read.

[[2 #]] provides the information that Sergey read two-ninths of the book in one day.
