Question

В первой фляге молока в 3 раза больше, чем во второй . Когда из первой фляги перелили во вторую 15л, молока в обеих флягах стало поровну. Сколько литров молока было в каждой фляге первоначально

Answer 1

1. 15*3 =45 количество в первой фляге
2. 45: 3= 15 во второй
ответ: 45 литров в первой, 15 во второй

Answer 2

Х-л молока во второй фляге. 3х- л молока в первой фляге. Составим уравнение. 3х-15=х+15. 2х=30. х=15 л молока было во второй фляге. 15*3= 45 л молока было в первой фляге. Проверка: 45-15=15+15. 30=30

Answer 3

Problem Analysis

We are given two bottles of milk, and the first bottle contains three times as much milk as the second bottle. When 15 liters of milk are poured from the first bottle into the second bottle, the amount of milk in both bottles becomes equal. We need to determine the initial amount of milk in each bottle.

Solution

Let's assume that the initial amount of milk in the second bottle is x liters. Since the first bottle contains three times as much milk as the second bottle, the initial amount of milk in the first bottle is 3x liters.

When 15 liters of milk are poured from the first bottle into the second bottle, the amount of milk in both bottles becomes equal. This means that the second bottle now contains x + 15 liters of milk, and the first bottle contains 3x - 15 liters of milk.

Since the amount of milk in both bottles is now equal, we can set up the following equation:

x + 15 = 3x - 15

Simplifying the equation, we get:

2x = 30

Dividing both sides of the equation by 2, we find:

x = 15

Therefore, the initial amount of milk in the second bottle is 15 liters, and the initial amount of milk in the first bottle is three times that amount, which is 3 * 15 = 45 liters.

Answer

The initial amount of milk in each bottle was 15 liters in the second bottle and 45 liters in the first bottle.
