Question

5)Вес Пети 21 кг. Когда он встал на весы, ВЗЯВ на руки кошку, весы показали 25кг 300 г. С котенком на руках Вася весит 22 КГ. Какой вес покажут весы, если на них усадить кошку и котёнка вместе? Ответ:​

Answer 1

Ответ:

5кг 300г

Пошаговое объяснение:

1) 25.3 - 21 = 4.3(кг) -кошка

2) 22 - 21 = 1(кг) -котенок

3) 4.3 + 1 = 5.3 (кг) кошка с котенком

Answer 2

Problem Analysis

We are given the weight of a person, Petia, which is 21 kg. When Petia stands on the scales while holding a cat, the scales show a weight of 25 kg 300 g. We are also given that when Vasya holds a kitten, his weight is 22 kg. We need to determine the weight that the scales will show if both the cat and the kitten are placed on them together.

Solution

To solve this problem, we need to find the weight of the cat and the weight of the kitten separately. Then, we can add these two weights to the weight of Petia to find the total weight that the scales will show.

Let's calculate the weight of the cat first. We know that the weight of Petia with the cat is 25 kg 300 g, and the weight of Petia without the cat is 21 kg. Therefore, the weight of the cat can be calculated as the difference between these two weights:

Weight of the cat = Weight of Petia with the cat - Weight of Petia without the cat

Weight of the cat = 25 kg 300 g - 21 kg

Now, let's calculate the weight of the kitten. We know that the weight of Vasya with the kitten is 22 kg, and the weight of Vasya without the kitten is 21 kg. Therefore, the weight of the kitten can be calculated as the difference between these two weights:

Weight of the kitten = Weight of Vasya with the kitten - Weight of Vasya without the kitten

Weight of the kitten = 22 kg - 21 kg

Finally, we can find the total weight that the scales will show by adding the weight of the cat, the weight of the kitten, and the weight of Petia:

Total weight on the scales = Weight of Petia + Weight of the cat + Weight of the kitten

Let's calculate the values:

Weight of the cat = 25 kg 300 g - 21 kg = 4 kg 300 g

Weight of the kitten = 22 kg - 21 kg = 1 kg

Total weight on the scales = 21 kg + 4 kg 300 g + 1 kg

Answer

The scales will show a weight of 26 kg 300 g when the cat and the kitten are placed on them together.

Note: The above calculations are based on the given information and assumptions.
