Question

Как решить задачу - ученик купил тетрадей в клетку в 3 раза больше чем тетрадей в линейку.Причем тетрадей в клетку было на 18 больше чем в линейку. Сколько всего тетрадей купил ученик. эта задача в 5 классе на части заранее спасибо

Answer 1

18:3=6 (т) в линейку купил ученик

Answer 2

Пусть количество тетрадей в линейку будет равно Х. Тогда количество тетрадей в клетку будет равно 3Х.

Согласно условию, количество тетрадей в клетку было на 18 больше, чем в линейку. То есть, 3Х = Х + 18.

Решим эту уравнение:

3Х - Х = 18 2Х = 18 Х = 18 / 2 Х = 9

Таким образом, ученик купил 9 тетрадей в линейку и 3 * 9 = 27 тетрадей в клетку.

Всего тетрадей ученик купил: 9 + 27 = 36 тетрадей.

Answer 3

Problem Analysis

To solve this problem, we need to determine the total number of notebooks the student bought. We are given that the student bought three times as many grid notebooks as lined notebooks, and that there were 18 more grid notebooks than lined notebooks.

Solution

Let's assume the number of lined notebooks the student bought is x. According to the problem, the student bought three times as many grid notebooks as lined notebooks, so the number of grid notebooks is 3x. We are also given that there were 18 more grid notebooks than lined notebooks, so we can set up the following equation:

3x = x + 18

To solve this equation, we can subtract x from both sides:

2x = 18

Then, we divide both sides by 2:

x = 9

Therefore, the student bought 9 lined notebooks. Since the number of grid notebooks is three times the number of lined notebooks, the student bought:

3 * 9 = 27 grid notebooks

To find the total number of notebooks the student bought, we add the number of lined notebooks and the number of grid notebooks:

9 + 27 = 36 notebooks

So, the student bought a total of 36 notebooks.

Answer

The student bought a total of 36 notebooks.
