Question

Масса двух чемоданов 20 кг. Масса одного из них в три раза меньше, чем масса другого. Найдите массу каждого чемодана. Решите действиями а не уравнением

Answer 1

Допустим, что масса одного 4 кг, тогда масса второго 4*3=12, 12+4=16-не верно. Тогда допустим, масса первого будет 5 кг, тогда масса второго 5*3=15, 15+5=20 верно.

Answer 2

Problem Analysis

We are given two suitcases with a total weight of 20 kg. The weight of one suitcase is three times less than the weight of the other suitcase. We need to find the weight of each suitcase.

Solution

Let's assume the weight of the larger suitcase is x kg. According to the problem, the weight of the smaller suitcase is three times less than the weight of the larger suitcase. Therefore, the weight of the smaller suitcase is x/3 kg.

We know that the total weight of both suitcases is 20 kg. So we can write the equation:

x + x/3 = 20

To solve this equation, we can multiply both sides by 3 to eliminate the fraction:

3x + x = 60

Simplifying the equation, we get:

4x = 60

Dividing both sides by 4, we find:

x = 15

Therefore, the weight of the larger suitcase is 15 kg, and the weight of the smaller suitcase is 15/3 = 5 kg.

Answer

The weight of the larger suitcase is 15 kg, and the weight of the smaller suitcase is 5 kg.
