Answer 1

300:10=30 г. осталось семечек
300-30 = 270 г. склевали воробьи 

Answer 2

Problem Analysis

In this problem, Kirill poured 300g of sunflower seeds into a bird feeder. Some sparrows came and ate a portion of the seeds. The remaining amount of seeds in the feeder is 10 times less than the original amount. We need to calculate how many grams of seeds the sparrows ate.

Solution

Let's assume that the amount of seeds the sparrows ate is represented by the variable `x`. We know that the remaining amount of seeds in the bird feeder is 10 times less than the original amount, which means the remaining amount is `300g - x`.

According to the problem, the remaining amount of seeds in the bird feeder is 10 times less than the original amount. This can be expressed as:

Remaining amount = 10 * (Original amount - Amount eaten)

Substituting the values we have:

300g - x = 10 * (300g - x)

Now, let's solve this equation to find the value of `x`, which represents the amount of seeds the sparrows ate.

Expanding the equation:

300g - x = 3000g - 10x

Combining like terms:

9x = 2700g

Dividing both sides by 9:

x = 300g

Therefore, the sparrows ate 300 grams of sunflower seeds.

Answer

The sparrows ate 300 grams of sunflower seeds.

Verification

To verify the answer, we can substitute the value of `x` back into the equation and check if it satisfies the condition.

300g - x = 10 * (300g - x)

300g - 300g = 10 * (300g - 300g)

0 = 10 * 0

The equation is true, which confirms that the sparrows ate 300 grams of sunflower seeds.
