Question

Определи массу лисы, белочки и обезьянки, если известно: масса зайца 3 кг, масса двух одинаковых зайцев на 1 кг меньше массы лисы; масса двух обезьян равна массе одного зайца и одной лисы; масса обезьяны на 1 кг больше массы одного зайца и одной белочки.

Answer 1

1) 3×2=6 (кг) - масса 2 зайцев.
2) 6+1=7 (кг) - масса лисы.
3) 7+6=13 (кг) - масса 2 обезьян.
4) 13-1=12 (кг) - масса белочки и зайчика.
5) 12-6=6 (кг) - масса белочки.
6) 13÷2=6 (ост.1) (кг) =6500 (г)- масса обезьяны.
Ответ:  7кг, 6 (ост. 1), 6кг.

Problem Analysis

We are given the following information: - The mass of a rabbit is 3 kg. - The mass of two identical rabbits is 1 kg less than the mass of a fox. - The mass of two monkeys is equal to the mass of one rabbit and one fox. - The mass of a monkey is 1 kg more than the mass of one rabbit and one squirrel.

We need to determine the masses of the fox, squirrel, and monkey.

Solution

Let's assign variables to the unknown masses: - Let f represent the mass of the fox. - Let s represent the mass of the squirrel. - Let m represent the mass of the monkey.

From the given information, we can write the following equations:

1. The mass of two identical rabbits is 1 kg less than the mass of a fox: 2 * 3 = f - 1.

2. The mass of two monkeys is equal to the mass of one rabbit and one fox: 2 * m = 3 + f.

3. The mass of a monkey is 1 kg more than the mass of one rabbit and one squirrel: m = 3 + s + 1.

Now, we can solve these equations to find the values of f, s, and m.

Solving the Equations

Let's solve the equations step by step:

1. From equation 1, we have: 2 * 3 = f - 1. Simplifying, we get: 6 = f - 1. Adding 1 to both sides, we get: f = 7.

2. From equation 2, we have: 2 * m = 3 + f. Substituting the value of f from equation 1, we get: 2 * m = 3 + 7. Simplifying, we get: 2 * m = 10. Dividing both sides by 2, we get: m = 5.

3. From equation 3, we have: m = 3 + s + 1. Substituting the value of m from equation 2, we get: 5 = 3 + s + 1. Simplifying, we get: 5 = 4 + s. Subtracting 4 from both sides, we get: s = 1.

Answer

Based on the given information, the masses of the animals are as follows: - The mass of the fox is 7 kg. - The mass of the squirrel is 1 kg. - The mass of the monkey is 5 kg.

Please note that these values are calculated based on the given information and may not represent real-world values.
