Question

реши задачу: хозяйка разлила 39 л молока и 45 л кваса в 28 банок поровну.Сколько банок с молоком и сколько банок с квасом получилось?

Answer 1

39+45=84(л) - всего

84:28=3(л) в одной банке

39:3=13(б.) - с молоком

45:3=15(б.) - с квасом

Answer 2

Problem Analysis

The problem states that the owner spilled 39 liters of milk and 45 liters of kvass into 28 jars equally. We need to determine how many jars contain milk and how many contain kvass.

Solution

To solve this problem, we can set up a system of equations based on the given information.

Let's assume that the number of jars containing milk is x and the number of jars containing kvass is y.

According to the problem, the total amount of milk spilled is 39 liters, and the total amount of kvass spilled is 45 liters. Since the liquids were divided equally among the jars, we can set up the following equations:

1. The total amount of milk in the jars is equal to 39 liters: x * (39 / 28) = 39

2. The total amount of kvass in the jars is equal to 45 liters: y * (45 / 28) = 45

We can simplify these equations by canceling out the common factors:

1. x * (39 / 28) = 39 becomes x * (3 / 2) = 39

2. y * (45 / 28) = 45 becomes y * (9 / 4) = 45

Now, we can solve these equations to find the values of x and y.

Calculation

Let's solve the first equation for x:

x * (3 / 2) = 39

Multiplying both sides by 2/3:

x = 39 * (2 / 3) x = 26

So, there are 26 jars containing milk.

Now, let's solve the second equation for y:

y * (9 / 4) = 45

Multiplying both sides by 4/9:

y = 45 * (4 / 9) y = 20

So, there are 20 jars containing kvass.

Answer

Therefore, there are 26 jars with milk and 20 jars with kvass.
