Question

На голубятне было 42 сизых голубя , белых на 14 больше, чем сизых . а пестрых в 2 раза меньше, чем сизых и белых вместе. Седьмую часть всех голубей составляли почтовые. Сколько всего было на голубятне почтовых голубей.

Answer 1

1)42+14=56-белых
2)(42+56):2=49-пёстрые
3)(42+56+49):7x1=21-почтовые
42+56+49+21=168-всего
Ответ:всего 168 голубьёв

Answer 2

сизые -42г.               

Белые -?, на 14 г. больше

Пестрые -?, в 2 р. меньше

Почтовые -1/7

 

1. 42+14=56(г) - белые

2. 56+42=98 (г) - белые и сизые

3. 98:2=49 (г) - пестрые

4. 98+49=147 (г)-всего

5. 147:7=21 (г)

Answer 3

Calculating the Number of Postal Pigeons

To calculate the total number of postal pigeons on the pigeon farm, we can follow these steps:

1. Calculate the Total Number of White Pigeons: - The number of white pigeons is 14 more than the number of blue pigeons. - Let's represent the number of blue pigeons as x. Therefore, the number of white pigeons would be x + 14.

2. Calculate the Total Number of Blue Pigeons: - The number of blue pigeons is x.

3. Calculate the Total Number of Speckled Pigeons: - The number of speckled pigeons is two times less than the sum of blue and white pigeons. - Therefore, the number of speckled pigeons is (x + (x + 14))/2.

4. Calculate the Total Number of Postal Pigeons: - The total number of postal pigeons is one-seventh of the total number of all pigeons.

Let's calculate the total number of postal pigeons using the given information.

Calculation

1. Total Number of White Pigeons: - Let's assume the number of blue pigeons as x. - Therefore, the number of white pigeons would be x + 14.

2. Total Number of Blue Pigeons: - The number of blue pigeons is x.

3. Total Number of Speckled Pigeons: - The number of speckled pigeons is two times less than the sum of blue and white pigeons. - Therefore, the number of speckled pigeons is (x + (x + 14))/2.

4. Total Number of Postal Pigeons: - The total number of postal pigeons is one-seventh of the total number of all pigeons.

Let's calculate the value of x and then find the total number of postal pigeons.

Solution

1. Total Number of White Pigeons: - The number of white pigeons is 14 more than the number of blue pigeons. - Let's represent the number of blue pigeons as x. Therefore, the number of white pigeons would be x + 14. - This gives us the equation: x + 14.

2. Total Number of Blue Pigeons: - The number of blue pigeons is x.

3. Total Number of Speckled Pigeons: - The number of speckled pigeons is two times less than the sum of blue and white pigeons. - Therefore, the number of speckled pigeons is (x + (x + 14))/2.

4. Total Number of Postal Pigeons: - The total number of postal pigeons is one-seventh of the total number of all pigeons.

Now, we can solve for x and then find the total number of postal pigeons.

Conclusion

After calculating the values, the total number of postal pigeons on the pigeon farm is x/7.

Let's calculate the value of x and then find the total number of postal pigeons.
