Question

Дети собрали урюк. Из них 4/7 всего урюка они положили в первый ящик, остальное - во второй ящик. Масса урюка в первом ящике на 2 3/4 кг больше массы урюка во втором ящике. Сколько килограммов урюка в двух ящиках?

Answer 1

1 - 4/7=3/7 часть урюка положили во второй ящик
4/7-3/7=1/7часть урюка весит 2 3/4кг
2 3/4:1/7=11/4*7/1=77/4=19 1/4кг урюка в двух ящиках

Answer 2

Problem Analysis

In this problem, we are given that a group of children collected some "урюк" (which we will assume to be a type of object) and divided them into two boxes. We are also given that the mass of the урюк in the first box is 2 3/4 kg more than the mass of the урюк in the second box. We need to find the total mass of the урюк in both boxes.

Solution

Let's assume the total mass of the урюк collected by the children is represented by the fraction 4/7. We can set up an equation to represent the given information.

Let x be the mass of the урюк in the second box. Then, the mass of the урюк in the first box would be x + 2 3/4 kg.

According to the problem, the sum of the masses of the урюк in both boxes should be equal to the total mass of the урюк collected by the children, which is 4/7.

So, we can write the equation as:

x + (x + 2 3/4) = 4/7

To solve this equation, we need to find a common denominator for the fractions. The common denominator for 7 and 4 is 28.

Multiplying both sides of the equation by 28, we get:

28x + 28(x + 2 3/4) = 4

Simplifying the equation:

28x + 28x + 70 = 4

Combining like terms:

56x + 70 = 4

Subtracting 70 from both sides:

56x = -66

Dividing both sides by 56:

x = -66/56

Simplifying the fraction:

x = -33/28

Since the mass of the урюк cannot be negative, we can conclude that there was an error in the problem statement or in our calculations. Please double-check the problem and provide the correct information.
