Question

Денис прочитал книгу за два дня. В первый день он прочитал на 1/9 всего объема книги больше, чем во второй. Какую часть книги Денис прочитал в первый день,а какую-во второй?

Answer 1

1 - вся книга
х - первый день
х-1/9 - второй день
х+(х-1/9)=1
2х=1ц.1/9
х=10/9*1/2
х=5/9 - первый день
5/9-1/9=4/9 - второй день

Answer 2

Solution:

To solve this problem, we can use a system of equations to represent the given information and then solve for the parts of the book Denis read on the first and second days.

Let's denote: - The total volume of the book as V. - The part of the book Denis read on the first day as x. - The part of the book Denis read on the second day as y.

We are given that: 1. Denis read the book in two days, so the sum of the parts he read on each day equals the total volume of the book: x + y = V. 2. Denis read more of the book on the first day than on the second day: x > y.

We can use these two equations to solve for x and y.

Calculation:

We can solve the system of equations using the given information.
