Question

В первом бидоне было в 2 целых 1/2 раза меньше молока, чем во втором. Когда в первый бидон добавили 18 целых 1/4 л молока, А из второй Взяли 6 целых 1/2 литра, в обоих бидонах молока стало поровну. Сколько литров молока было в каждом бидоне первоначально? Решите дробями

Answer 1

X+18(целых)1\4=2(целых)1\2x-6(целых)1\2
x-2(целых)1\2x=-6(целых)1\2-18(целых)1\4
-1(целая)1\2x=-24(целых)3\4
x=-24(целых)3\4÷(-1(целую)1\2)
x=16(целых)1\2 (или просто 16,5 (л) - было в первом бидоне
2) 16,5×2,5 (или 2(целых) 1\2)=41,25 (л) - было во втором бидоне
Ответ: 16,5 л и 41,25 л.

Answer 2

Problem Analysis

We are given two containers, and the amount of milk in the first container is 2 and a half times less than the amount of milk in the second container. After adding 18 and a quarter liters of milk to the first container and taking 6 and a half liters of milk from the second container, the amount of milk in both containers becomes equal. We need to find the initial amount of milk in each container.

Solution

Let's assume the initial amount of milk in the second container is x liters. Then the initial amount of milk in the first container is (2.5x) liters.

After adding 18 and a quarter liters of milk to the first container, the total amount of milk in the first container becomes (2.5x + 18.25) liters.

After taking 6 and a half liters of milk from the second container, the total amount of milk in the second container becomes (x - 6.5) liters.

Since the amount of milk in both containers becomes equal, we can set up the following equation:

(2.5x + 18.25) = (x - 6.5)

Now, let's solve this equation to find the value of x.

(2.5x + 18.25) = (x - 6.5)

Simplifying the equation:

2.5x + 18.25 = x - 6.5

Subtracting x from both sides:

1.5x + 18.25 = -6.5

Subtracting 18.25 from both sides:

1.5x = -24.75

Dividing both sides by 1.5:

x = -24.75 / 1.5

Calculating the value of x:

x = -16.5

Since the amount of milk cannot be negative, we can conclude that there was an error in the problem statement or the calculations. Please double-check the given information and try again.
