Question

Масса курицы на 3 раза меньше чем масса кролика. Масса кролика на 4кг больше чем масса курицы. Найдите массу курицы и кролика.

Answer 1

Пусть х кг - масса курицы, а у кг - масса кролика, тогда:
у = 3х и у = х + 4
★ 3х = х + 4
3х - х = 4
2х = 4
х = 4/2
х = 2
★ х = 2 и у = 3х
х = 2 и у = 3 × 2
х = 2 и у = 6
Ответ: 2 кг - масса курицы; 6 кг - масса кролика.

Answer 2

Problem Analysis

To find the mass of the chicken and the rabbit, we are given two pieces of information: 1. The mass of the chicken is three times less than the mass of the rabbit. 2. The mass of the rabbit is 4 kg more than the mass of the chicken.

Let's assign variables to the unknown masses: - Let C be the mass of the chicken. - Let R be the mass of the rabbit.

Based on the given information, we can write two equations: 1. C = R/3 (The mass of the chicken is three times less than the mass of the rabbit.) 2. R = C + 4 (The mass of the rabbit is 4 kg more than the mass of the chicken.)

We can solve these equations to find the values of C and R.

Solution

Let's solve the equations to find the mass of the chicken and the rabbit.

From equation 1, we have C = R/3.

Substituting this value of C into equation 2, we get R = (R/3) + 4.

To solve this equation, we can multiply both sides by 3 to eliminate the fraction: 3R = R + 12.

Next, we can subtract R from both sides: 2R = 12.

Finally, we can divide both sides by 2 to solve for R: R = 6.

Now that we have the mass of the rabbit, we can substitute this value into equation 1 to find the mass of the chicken: C = 6/3 = 2.

Therefore, the mass of the chicken is 2 kg and the mass of the rabbit is 6 kg.

Answer

The mass of the chicken is 2 kg and the mass of the rabbit is 6 kg.
