Answer 3

Calculation of Remaining Books to Read

To determine the remaining books that Alibek needs to read, we can subtract the number of books he has already read from the total number of books.

Given the information provided: - On the first day, Alibek read 11/15 books. - On the second day, he read -1/30 books.

To find the total number of books, we need to add the fractions together: 11/15 + (-1/30)

To add fractions, we need a common denominator. In this case, the least common multiple (LCM) of 15 and 30 is 30. Let's convert the fractions to have a denominator of 30:

11/15 = 22/30 -1/30 = -1/30

Now we can add the fractions: 22/30 + (-1/30) = 21/30

Therefore, Alibek has read 21/30 of the book.

Answer

Alibek has 21/30 of the book left to read.
