Question

Очень надо! Дам 50 баллов. В одном ящике 12 кг яблок, что в 1 5/7 раза больше, чем во втором, и в 1 1/12 раза меньше, чем в третьем. Сколько килограмм яблок в трёх ящиках?

Answer 1

Ответ:

12÷1 5/7=7

12×1 1/12=13

Ответ: в 1 ящике 12кг яблок, во втором ящике 7кг яблок, а в третьем 13кг яблок

Answer 2

Problem Analysis

We are given information about three boxes of apples. The weight of the apples in the first box is 12 kg, which is 1 5/7 times greater than the weight of the apples in the second box. The weight of the apples in the first box is also 1 1/12 times smaller than the weight of the apples in the third box. We need to find the weight of the apples in the three boxes.

Solution

Let's assume the weight of the apples in the second box is x kg.

According to the given information: - The weight of the apples in the first box is 1 5/7 times greater than the weight of the apples in the second box. Therefore, the weight of the apples in the first box is (1 + 5/7) times the weight of the apples in the second box, which is (12/7) * x kg. - The weight of the apples in the first box is 1 1/12 times smaller than the weight of the apples in the third box. Therefore, the weight of the apples in the first box is (1 - 1/12) times the weight of the apples in the third box, which is (11/12) * y kg, where y is the weight of the apples in the third box.

We can set up the following equations based on the above information:

Equation 1: (12/7) * x = 12 kg Equation 2: (11/12) * y = 12 kg

Let's solve these equations to find the values of x and y.

Solving the Equations

From Equation 1, we can solve for x: (12/7) * x = 12 kg x = (12 kg * 7) / 12 x = 7 kg

From Equation 2, we can solve for y: (11/12) * y = 12 kg y = (12 kg * 12) / 11 y ≈ 13.09 kg

Therefore, the weight of the apples in the three boxes is as follows: - First box: 12 kg - Second box: 7 kg - Third box: 13.09 kg (approximately)

Answer

The weight of the apples in the three boxes is approximately: - First box: 12 kg - Second box: 7 kg - Third box: 13.09 kg
