Question

С молочной фермы 14% всего молока отправили в детский сад и 3/7 всего молока - в школу. Сколько молока отправили в школу, если в детский сад отправили 49л. пожалуйста помогите решить задачу и напишите решение по действиям.

Answer 1

Дано:
Отправили в дет. сад - 14% молока=49 л
Отправили в школу - 3/7 всего молока
Найти:
Отправили в школу - ? л молока
РЕШЕНИЕ
1) Найдём с помощью пропорции сколько литров молока было всего (100%), зная что 14 % отправленных в детский сад составляют 49 литров.
49 литров молока - 14 %
всего литров молока -  100%
49×100%÷14%=4900÷14=350 литров.
2) От 350 литров молока (7/7=1) отправили 3/7 в школу. Посчитаем сколько литров молока отправили в школу:
350 литров - 1 часть
отправили в школу, л - 3/7 части
350×3/7÷1=1050÷7=150 (л) - отправили в школу
ОТВЕТ: в школу отправили 150 литров молока.

Answer 2

Problem Analysis

We are given that 14% of the total milk from a dairy farm is sent to a daycare, and 3/7 of the total milk is sent to a school. We are also given that 49 liters of milk are sent to the daycare. We need to find out how much milk is sent to the school.

Solution

Let's assume the total amount of milk from the dairy farm is x liters.

According to the problem, 14% of the total milk is sent to the daycare. So, the amount of milk sent to the daycare is 14% of x.

Similarly, 3/7 of the total milk is sent to the school. So, the amount of milk sent to the school is (3/7) of x.

We are given that 49 liters of milk are sent to the daycare. So, we can set up the following equation:

14% of x = 49 liters

To find the amount of milk sent to the school, we can use the equation:

(3/7) of x = ?

Let's solve the equation to find the value of x and then calculate the amount of milk sent to the school.

Calculation

To find the value of x, we can rearrange the equation:

14% of x = 49 liters

0.14 x = 49

Dividing both sides of the equation by 0.14:

x = 49 / 0.14

x ≈ 350 liters

Now, we can calculate the amount of milk sent to the school:

(3/7) of x = (3/7) * 350

(3/7) of x ≈ 150 liters

Answer

Therefore, approximately 150 liters of milk were sent to the school.
