Question

В ведре было 40 кружек молока. После того,как из ведра отлили какое-то количество молока, то в нем осталось молока в 7 раз больше,чем отлили.Сколько молока отлили из ведра?

Answer 1

Значит отлили 1 часть молока , а осталось 7 частей молока . Всего было в ведре :1 + 7 = 8 частей молока . Отсюда имеем , что отлили молока 40 / 8 * 1 = 5 кружек молока

Answer 2

Пусть отлили х кружек, тогда осталось 7х кружек, в сумме это 40 кружек:
х+7х=40
8х=40
х=5 кружек

Answer 3

Problem Analysis

We are given that there were 40 cups of milk in a bucket. After pouring out some amount of milk, the remaining milk in the bucket is 7 times more than the amount poured out. We need to determine how much milk was poured out from the bucket.

Solution

Let's assume that x cups of milk were poured out from the bucket. According to the given information, the remaining milk in the bucket is 7 times more than the amount poured out. This can be expressed as:

Remaining milk = 7 * Poured out milk

We also know that the initial amount of milk in the bucket was 40 cups. So, the equation becomes:

40 - x = 7x

Simplifying the equation:

40 = 8x

Dividing both sides by 8:

x = 40/8 = 5

Therefore, 5 cups of milk were poured out from the bucket.

Answer

5 cups of milk were poured out from the bucket.

Explanation

We can verify the answer by substituting the value of x back into the equation:

40 - 5 = 7 * 5

35 = 35

The equation holds true, confirming that the answer is correct.
