Question

В двух бидонах 24 л молока. Сколько литров молока в каждом бидоне, если 15% первого равно 75% второго?

Answer 1

В первом бедоне x литров, во втором 5x литров. ( 3/20=3/4 ; 1/5=1)

x+5x=24 литров

6x=24

x=4л

В первом бедоне 4 литра, во втором 4*5=20 литров.

Ответ : 4 ; 20.

Answer 2

x -литров в первом

y  литров во втором

x+y=24

0.15*x=0.75*y

решим систему

х = 20л

у = 4л

Answer 3

Calculating the Amount of Milk in Each Container

To solve this problem, we can use the information given in the question to set up a system of equations. Let's denote the amount of milk in the first container as x liters and the amount of milk in the second container as y liters. We are given that the total amount of milk in both containers is 24 liters, so we have the equation:

x + y = 24

We are also given that 15% of the first container is equal to 75% of the second container. This can be expressed as:

0.15x = 0.75y

Now, we can solve these two equations to find the values of x and y.

Solving the Equations

First, let's solve the equation x + y = 24 for x: x = 24 - y

Now, substitute x = 24 - y into the equation 0.15x = 0.75y: 0.15(24 - y) = 0.75y

Solving for y: 3.6 - 0.15y = 0.75y 3.6 = 0.9y y = 4

Now that we have the value of y, we can find the value of x: x = 24 - 4 x = 20

Conclusion

Therefore, the amount of milk in the first container is 20 liters and the amount of milk in the second container is 4 liters.
