Question

Вася на окошке повесил кормушку. В первый день к кормушке прилетело много птиц. Во второй - в два раза больше. В третий - в два раза меньше, чем в первый. Сколько птичек прилетало к кормушке каждый день, если всего за три дня клевали зёрнышки в кормушке 252 птички?

Answer 1

Х+2х+х/2=252
2х+4х+х=504
7х=504
х=72
72 - в первый день
72*2=144 - во второй день
72:2=36 - третий день

Answer 2

Calculating the Number of Birds Visiting the Feeder

To calculate the number of birds visiting the feeder each day, we can use the information provided and work through the problem step by step.

1. Establishing the Variables: - Let's denote the number of birds that visited the feeder on the first day as x. - On the second day, the number of birds that visited the feeder was 2x. - On the third day, the number of birds that visited the feeder was (1/2)x.

2. Forming Equations: - We know that the total number of birds that visited the feeder over the three days is 252. Therefore, we can form the equation: x + 2x + (1/2)x = 252.

3. Solving for x: - To solve for x, we can combine the terms on the left-hand side of the equation: (5/2)x = 252. - Multiplying both sides by 2/5 gives us: x = (252 * 2) / 5.

4. Calculating the Number of Birds Each Day: - Now that we have the value of x, we can calculate the number of birds that visited the feeder each day: - On the first day: x - On the second day: 2x - On the third day: (1/2)x

Conclusion

By following this approach, we can calculate the number of birds that visited the feeder each day based on the given information.
