Question

Помогите плиз. В два кувшина налили молоко. В первом кувшине было 5,4 л молока. Когда из первого кувшина перелили 1,2 л молока во второй, то в нем стало 2,8 л молока больше, чем осталось в первом. Сколько литров молока было во втором кувшине?

Answer 1

1 кувшин - 5,4 л, перелили 1,2 л во 2
2 кувшин - ?, на 2,8 больше, чем осталось в 1
(х + 1,2) - (5,4 - 1,2) = 2,8
(x + 1,2) - 4,2 = 2,8
x + 1,2 = 2,8 + 4,2
x + 1,2 = 7
x = 7 - 1,2
x = 5,8
Ответ: x = 5,8

Answer 2

Problem Analysis

We are given two pitchers of milk. The first pitcher initially contains 5.4 liters of milk. When 1.2 liters of milk are poured from the first pitcher into the second pitcher, the second pitcher ends up with 2.8 liters more milk than what remains in the first pitcher. We need to determine the amount of milk in the second pitcher.

Solution

Let's denote the amount of milk in the second pitcher as x liters. According to the problem, when 1.2 liters of milk are poured from the first pitcher into the second pitcher, the second pitcher ends up with 2.8 liters more milk than what remains in the first pitcher.

So, the amount of milk remaining in the first pitcher after pouring 1.2 liters into the second pitcher is 5.4 - 1.2 = 4.2 liters.

According to the problem, the second pitcher has 2.8 liters more milk than what remains in the first pitcher. Therefore, we can set up the equation:

x = 4.2 + 2.8

Simplifying the equation, we find:

x = 7 liters

Therefore, there are 7 liters of milk in the second pitcher.

Answer

There are 7 liters of milk in the second pitcher.
