Question

Тотошка и его друг Гектор решили сосчитать всех птиц в хозяйстве Джона и Анны. Оказалось, что на птичьем дворе живут 40 уток. Это на 70 птиц меньше,чем кур, и на 12 больше,чем индеек. Сколько уток,кур и индеек живут на птичьем дворе Джона и Анны?

Answer 1

40+70=110кур

40-12=28индеек

110+40+28=178птиц всего

Answer 2

Если 40 уток-это на 70 меньше,чем кур,значит кур на 70 больше,чем уток,и,соответственно индеек на 12 меньше,чем уток

Ут.-40п

К-?,на 70 >чем Ут        }-? всего

Ин.-?,на 12<,чем 

40+70=110(п)-кур

40-12=28(п)-индеек

40+110+28=178(п)-всего 

 

Answer 3

Problem Analysis

To solve this problem, we need to determine the number of ducks, chickens, and turkeys on John and Anna's poultry yard. We are given the following information: - There are 40 ducks on the poultry yard. - The number of ducks is 70 less than the number of chickens. - The number of ducks is 12 more than the number of turkeys.

Let's use variables to represent the number of ducks, chickens, and turkeys: - Let D represent the number of ducks. - Let C represent the number of chickens. - Let T represent the number of turkeys.

Solution

We can set up a system of equations based on the given information and solve it to find the values of D, C, and T.

1. The number of ducks is 70 less than the number of chickens: D = C - 70.

2. The number of ducks is 12 more than the number of turkeys: D = T + 12.

3. There are 40 ducks on the poultry yard: D = 40.

Now we can solve this system of equations to find the values of D, C, and T.

Substituting equation 3 into equations 1 and 2, we have: 40 = C - 70 and 40 = T + 12.

Simplifying these equations, we get: C = 110 and T = 28.

Therefore, there are 40 ducks, 110 chickens, and 28 turkeys on John and Anna's poultry yard.

Answer

On the poultry yard of John and Anna, there are: - 40 ducks - 110 chickens - 28 turkeys.
