Учень прочитав 24 сторінки, що склало 16% від загального обсягу сторінок.Скільки сторінок у книжці?


shahbazovelman97: Можно воспользоваться пропорцией для решения данной задачи. Пусть общее количество страниц в книге равно Х. Тогда уравнение будет выглядеть следующим образом:

24 / Х = 16 / 100

Разрешая уравнение относительно X, получим:

X = 24 * 100 / 16

X = 150

Значит, в книге 150 страниц.

Перший спосіб:

Нехай загальна кількість сторінок у книжці буде x, тоді:

0.16x = 24

x = 24 : 0.16

x = 150


Другий спосіб:

(24 : 16) * 100 = 150

Отже, у книжці 150 сторінок
