Question

Стодент прочитав книжку за два дні за перший день 46% а за другий на 32 сторінки більше ніж за перший . скільки сторінок в книжці?

Answer 1

46% - сотая часть числа

0,46х (стр) - в первый день; 0,46х + 32 - во второй; всех страниц х

0,46х + 0,46х +32 = х

0,92х - х = - 32

-0,08х = - 32

х = - 32 : (- 0,08) = 400 (стр) - всего

400 * 0,46 = 184 (стр) - прочитал в первый день
184 + 32 = 216 (стр) - во второй день

Проверка: 184 + 216 = 400 стр.

Ответ: в книге 400 страниц.

Answer 2

Calculation of the Number of Pages in the Book

To calculate the number of pages in the book, we need to determine the number of pages read on the first day and the number of pages read on the second day. We are given that on the first day, the student read 46% of the book, and on the second day, they read 32 pages more than on the first day.

Let's assume that the total number of pages in the book is represented by the variable x.

On the first day, the student read 46% of the book, which can be expressed as 0.46x.

On the second day, the student read 32 pages more than on the first day, so the total number of pages read on the second day is 0.46x + 32.

To find the total number of pages in the book, we can set up the following equation:

0.46x + 32 = x

Simplifying the equation, we get:

0.54x = 32

Dividing both sides of the equation by 0.54, we find:

x = 32 / 0.54

Using a calculator, we can determine that x is approximately 59.26.

Therefore, the book has approximately 59 pages.

Please note that the calculation assumes that the student read the same number of pages each day and that the book has a consistent number of pages throughout.
