Question

Реши задачу. Вычисли и запиши ответ. В двух рулонах было 864 м плёнки. Сколько плёнки было в каждом рулоне, если в одном рулоне в 7 раз больше, чем в другом

Answer 1

Ответ:в первом рулоне было 425м пленки,во 2 рулоне 439м пленки

Answer 2

Пусть в одном из рулонов было х плёнки, тогда в другом 7х
составим уравнение:
х+7х=864
8х=864
х=108

864-108=756 м плёнки было в другом рулоне

Answer 3

Problem Analysis

We are given that there are 864 meters of film in two rolls, and one roll has 7 times more film than the other. We need to find the amount of film in each roll.

Solution

Let's assume the amount of film in the smaller roll is x meters. According to the problem, the larger roll has 7 times more film than the smaller roll.

So, the amount of film in the larger roll is 7x meters.

The total amount of film in both rolls is given as 864 meters.

Therefore, we can write the equation:

x + 7x = 864

Simplifying the equation:

8x = 864

Dividing both sides by 8:

x = 864 / 8

Calculating the value of x:

x = 108

So, the smaller roll has 108 meters of film, and the larger roll has 7 times more film, which is 7 * 108 = 756 meters.

Answer

Therefore, there are 108 meters of film in the smaller roll and 756 meters of film in the larger roll.
