Question

У семи одноклассников было поровну наклеек с футболистами, причём всего у них было больше 120, но меньше 200 наклеек. Когда в их класс пришёл новый ученик, каждый мальчик подарил ему восьмую часть своих наклеек. Сколько наклеек отдал каждый?

Answer 1

общее количество наклеек  должно быть кратно 7 и 8

7*8=56

120<[56*3=168] <200

значит всего у них было 168 наклеек

168/7= 24наклейки  у каждого мальчика

24/8= 3 наклейки отдал каждый мальчик

Answer 2

Ответ:

Пошаговое объяснение:

количество наклеек должно быть кратно 7 и 8

7×8=56

120< [56×3=168] <200

168÷7=24 наклейки было у каждого мальчика

24÷8=3 наклейки подарил каждый мальчик

Answer 3

Solving for the Number of Stickers Initially Owned

To solve this problem, we can use algebra to represent the given information and solve for the number of stickers each of the seven classmates initially owned.

Let's denote the number of stickers each classmate initially owned as x. According to the given information, the total number of stickers owned by the seven classmates is more than 120 but less than 200. We can represent this as an inequality:

120 < 7x < 200

To find the value of x, we can divide each part of the inequality by 7:

120/7 < x < 200/7

Let's calculate the values:

17.14 < x < 28.57

Since the number of stickers must be a whole number, the possible values for x are 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, and 28.

Distributing Stickers to the New Student

Now, let's calculate how many stickers each classmate gave to the new student. Each classmate gave the new student one-eighth of their stickers.

We can calculate this by dividing the initial number of stickers owned by each classmate by 8.

Let's calculate the number of stickers each classmate gave to the new student using the possible values of x: - For x = 18: 18 / 8 = 2.25 - For x = 19: 19 / 8 = 2.375 - For x = 20: 20 / 8 = 2.5 - For x = 21: 21 / 8 = 2.625 - For x = 22: 22 / 8 = 2.75 - For x = 23: 23 / 8 = 2.875 - For x = 24: 24 / 8 = 3 - For x = 25: 25 / 8 = 3.125 - For x = 26: 26 / 8 = 3.25 - For x = 27: 27 / 8 = 3.375 - For x = 28: 28 / 8 = 3.5

Conclusion

Based on the calculations, each classmate gave the new student the following number of stickers: - For x = 18: 2 stickers - For x = 19: 2 stickers - For x = 20: 2 stickers - For x = 21: 2 stickers - For x = 22: 2 stickers - For x = 23: 2 stickers - For x = 24: 3 stickers - For x = 25: 3 stickers - For x = 26: 3 stickers - For x = 27: 3 stickers - For x = 28: 3 stickers

Therefore, each classmate gave the new student either 2 or 3 stickers, depending on the initial number of stickers they owned.
