Answer 2

Problem:

В прятки играли 12 ребят, к ним присоединились 3 девочки и 4 мальчика. Сколько всего ребят стали играть в прятки? Решите задачу тремя способами.

Solution 1:

To find the total number of children playing hide and seek, we can add the number of children who were already playing with the number of children who joined the game.

Given: - Number of children already playing: 12 - Number of girls who joined: 3 - Number of boys who joined: 4

To find the total number of children playing hide and seek, we can add these numbers together:

12 (children already playing) + 3 (girls who joined) + 4 (boys who joined) = 19

Therefore, the total number of children who started playing hide and seek is 19.

Solution 2:

Another way to solve this problem is by counting the number of children in each group and then adding them together.

Given: - Number of children already playing: 12 - Number of girls who joined: 3 - Number of boys who joined: 4

To find the total number of children playing hide and seek, we can count the number of children in each group and then add them together:

12 (children already playing) + 3 (girls who joined) + 4 (boys who joined) = 19

Therefore, the total number of children who started playing hide and seek is 19.

Solution 3:

We can also solve this problem by first finding the total number of children who joined the game and then adding them to the number of children already playing.

Given: - Number of children already playing: 12 - Number of girls who joined: 3 - Number of boys who joined: 4

To find the total number of children playing hide and seek, we can first find the total number of children who joined the game:

3 (girls who joined) + 4 (boys who joined) = 7

Then, we add this number to the number of children already playing:

12 (children already playing) + 7 (children who joined) = 19

Therefore, the total number of children who started playing hide and seek is 19.

In all three solutions, we find that the total number of children who started playing hide and seek is 19.
