Ответы на вопрос

Ответ:
Пошаговое объяснение:
3/4 = 3 : 4 = 0,75 кг
0,75 кг = 360 рублей
2,5 кг = х рублей
0,75/2,5 = 360/х
х = 360 * 2,5 / 0,75
х = 900/0,75
х = 1200
Ответ: 1200 рублей стоит 2,5 кг конфет



Problem:
The problem states that 3/4 of a certain quantity of candies were purchased for 360 rubles. We need to determine the cost of 2.5 kg of these candies.Solution:
To solve this problem, we can set up a proportion using the given information. Let's assume that the total quantity of candies is represented by "x". We know that 3/4 of x is equal to 360 rubles.Let's set up the proportion:
(3/4)x = 360
To find the value of x, we can multiply both sides of the equation by 4/3:
x = (4/3) * 360
Now, we can calculate the value of x:
x = 480
So, the total quantity of candies is 480.
Next, we need to find the cost of 2.5 kg of these candies. To do this, we can set up another proportion using the total quantity of candies and the cost of 2.5 kg.
Let's assume that the cost of 2.5 kg of candies is represented by "y". We know that 480 candies cost 360 rubles. We also know that 2.5 kg is equivalent to 2500 grams.
Let's set up the proportion:
480 candies / 360 rubles = 2500 grams / y rubles
To find the value of y, we can cross-multiply and solve for y:
480 * y = 360 * 2500
y = (360 * 2500) / 480
Now, we can calculate the value of y:
y ≈ 1875 rubles
Therefore, 2.5 kg of these candies cost approximately 1875 rubles.
Answer: 2.5 kg of these candies cost approximately 1875 rubles.
