Question

Срочно Волонтери половину куплених іграшок віддали в дитячий будинок, половину решти — до лікарні, а остачу розділили порівну між двома дитячими садочками. Скільки всього було іграшок, якщо дитячі садочки отримали по 20 штук?

Answer 1

Пошаговое объяснение:

20+20=40(іграшок)- віддали до дитячих садків разом; віддали до лікарні

40+40=80(іграшок)- віддали до дитячих садків і лікарні разом

80+80=160(іграшок)- всього було

Answer 2

Ответ:

20 * 2 * 2 = 80

Answer 3

Solution:

To solve this problem, we can work backwards from the information given about the number of toys received by the two kindergartens.

Let's denote the total number of toys as T.

1. The first step is to find the number of toys that were given to the kindergartens. We know that each kindergarten received 20 toys, so the total number of toys given to the kindergartens is 20 * 2 = 40.

2. The next step is to find the number of toys that were given to the hospital. We know that half of the remaining toys were given to the hospital. Therefore, the number of toys given to the hospital is (T - 40) / 2.

3. Finally, we can find the number of toys that were given to the children's home. Since half of the toys were given to the children's home, the number of toys given to the children's home is also (T - 40) / 2.

Now, we can set up an equation to solve for the total number of toys, T:

(T - 40) / 2 + (T - 40) / 2 + 40 = T

Let's solve for T:

(T - 40) + (T - 40) + 80 = 2T

2T - 80 + 80 = 2T

2T = 2T

This equation shows that the total number of toys, T, can be any value, as the equation simplifies to 0 = 0. Therefore, there are an infinite number of solutions for the total number of toys.

So, based on the given information, we cannot determine the exact total number of toys.
