Answer 1

1) 13-1=12 тарелок весят 4 миски
2) 12:4=3 тарелки весит 1 миска
3) 3*2=6 тарелок весят две миски
4) 6+1=7 тарелок весит одна кастрюля
Ответ: 7 тарелок
Проверка: 7+6=13

Answer 2

Problem Analysis

We are given the following information: - 2 bowls and 1 pot of porridge weigh the same as 13 plates. - 1 pot weighs the same as 2 bowls and 1 plate.

We need to determine how many plates are in the pot.

Solution

Let's assume the weight of one plate is P and the weight of one bowl is B. Since the weight of the pot is the same as 2 bowls and 1 plate, we can write the equation:

2B + P = 1 pot We are also given that 2 bowls and 1 pot of porridge weigh the same as 13 plates. We can write this equation as:

2B + 1 pot = 13P Now, let's substitute the value of 1 pot from equation into equation:

2B + (2B + P) = 13P

Simplifying the equation:

4B + P = 13P

Subtracting P from both sides:

4B = 12P

Dividing both sides by 4:

B = 3P

Now, we know that the weight of one bowl is 3 times the weight of one plate.

To find the number of plates in the pot, we need to substitute the value of B in equation:

2(3P) + P = 1 pot

Simplifying the equation:

6P + P = 1 pot

7P = 1 pot

Therefore, there is 1/7 of a plate in the pot.

Answer

There is 1/7 of a plate in the pot.

Explanation

Based on the given information, we can determine that the weight of one bowl is 3 times the weight of one plate. Using this information, we can calculate that there is 1/7 of a plate in the pot.
