Calculation of the Number of Books Bound by Students

To calculate the total number of books bound by the students over three days, we need to add up the number of books bound each day.

On the first day, the students bound 2/7 of all the books. On the second day, they bound 1/3 of all the books. And on the third day, they bound the remaining 40 books.

To find the total number of books bound, we can add up the fractions from the first two days and then add the remaining books from the third day.

Let's calculate it step by step:

1. First day: 2/7 of all the books. 2. Second day: 1/3 of all the books. 3. Third day: 40 books.

To find the total number of books bound, we can add these three values together.
